Errata - Physical Chemistry, 1/e Although many efforts were made to make the text and solutions manuals as error-free as possible, inevitably some typos or misprints are present.  This page lists them (and I hope I can find a equation editor for web pages), with the exception of italicizing variables.  I will keep this as up-to-date as possible.  If you find an error or typo that is not listed here, please let me know by emailing me .  Unless you state otherwise, I will credit you with the correction.

Many thanks to everyone for their contributions.  I appreciate everybody's understanding of the tribulations that accompany a first-printing text.

Reprinting will happen soon!  All of these will be corrected in the new printing, ready for new adoptions!  -dwb

(Thanks to Dr. Joseph Brom, University of St. Thomas.  Posted 9/6/02.)

page 14 - Example 1.5 - There should be an extra set of parentheses in the left side of the second equation so that the substitutions for the "V-nb" term are properly multiplied together.  The numerical solution is correct, however.
(Thanks to Kristy Castonguay, University of Maryland.  Posted 9/10/03.)

(Thanks to Dr. Joseph Brom, University of St. Thomas.  Posted 9/19/02.)

page 90 - Four equations involving qrev - Although it states at the bottom of the derivation that the 'equals' sign in the equations that precede it refers to the reversible process, the 'rev' label on q should be omitted so that the 'less than' sign in those equations is also applicable in irreversible situations.
(Thanks to Dr. Jonathan Mitschele, Saint Joseph's College.  Posted 2/12/03.)

(Thanks to Joshua Czerwinski, John Carroll University.  Posted 10/21/03.)

page 129 - Equation 5.13 - The activity variable in the numerator should have a subscript "i" on it. Also, the denominator should read "j reactants", not "j products".
(Discovered by author.  Posted 10/10/02.  Thanks also to Dan Graesser, University of Illinois at Urbana; posted 10/13/03.)

page 131 - third equation (unnumbered) on page et seq. - M i should refer to the molar mass of the solvent, not the solute.

(Thanks to Charcie Lee, Cleveland State University.  Posted 10/30/02.)

page 197 - there are four places where xsolute should be xsolvent.
(Discovered by author.  Posted 10/30/02.)

page 200 - Example 7.16 - The first approximation step is incorrect; you can't substitute the total volume for the molar volume.  This introduces a error factor of 55 or so.  The number of moles in the solution should be 2.18x10-6 mol, and the final molecular weight would be 4590 g/mol.  (Don't ask how I got 815,000....)

page 220, 221, exercise 8.23 - Equaiton 8.30 should have a minus sign inside the parentheses, not a plus sign.  This affects the answer to Example 8.6 on page 221 and the answer to exercise 8.23 as well.
(Thanks to Tommie McSherry, New Mexico Institute of Mining and Technology.  Posted 11/11/03.)

page 221 - Equation 8.31 - there should be a minus side on the right side of the equation; caused by an errant minus sign on the equation before it.
(Thanks to Charcie Lee, Cleveland State University.  Posted 11/14/02.)

page 227, top half of page - the discussion should be 'total free energy', not 'total chemical potential' (since chemical potential is a partial molar quantity).  Equation 8.42, the unnumbered equation immediately following, and equation 8.45 should be expressions for G, not mu.
(Thanks to Dr. Timothy Thomas, University of Missouri - Kansas City.  Posted 2/19/04.)

page 233 - Example 8.12 - In the last line of part a, it should be 0.0188, not 0.00188.  The final answer is thus 0.360 V, not 0.377 V.

page 272 - Exercise 9.38 - the equation that should be integrated here is equation 9.23, the infinitesimal power flux form of Planck's law (otherwise you get a different form of the Stefan-Boltzman constant).
(Thanks to Dr. Tim Thomas, University of Missouri at Kansas City.  Posted 1/27/04.)

page 290 - first line of continued example - The last parenthetical expression should read (kAsinkx - kBcos kx ) - that is, the sine and cosine functions are switched.  However, the final answer is correct.
(Thanks to Melissa McCulloch, Cleveland State University.  Posted 2/4/03.)

page 302 - Example 10.14 - In the second part where the average value is separated into dimensions, one of the normalization constants in the y dimension has a in the denominator; it should be b .  This is repeated on the next page.  However, it does not effect the final answer in the example.
(Thanks to R. Michael Roller, University of Illinois Urbana-Champaign.  Posted 12/22/03.)

page 311 - Exercise 10.8(d) - To be consistent with the answer in the back of the book and the solutions manual, the exponent should have a negative sign in it.
(Thanks to Dr. Anthony K. Grafton, Lyon College.  Posted 9/13/04.)

page 324 - Example 11.4 - in the next to last equation, the unit should be s-1, not s.  However, this does not affect the answer.
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 2/16/05.)

(Thanks to Kristen Ewing, Indiana University.  Posted3/18/04.)

page 343 - Table 11.3 - the Legendre Polynomial for l - 2 and m = 0 should be "1/4 sqrt(10) * (3 cos(theta)^2 - 1)" [the three is missing as a multiplier on the cosine].
(Thanks to Dr. Chad M. Rienstra, University of Illinois at Urbana-Champaign .  Posted December 9, 2003.)

pages 348 & 349 - Figures 11.14 and 11.15 - The lengths of the Ltot vector should read "the square root of six times h-bar" not "the square root of 6h-bar".  The radical sign should not be extended over the h-bar.
(Discovered by author.  Posted 2/11/03.)

page 355, Table 11.4 - In the (3,0,0) wavefunction, the last term inside the parentheses should have a Z2 factor, not just Z.
(Thanks to Dr. Judith Harrison, United States Naval Academy.  Posted 3/14/05.)

(Thanks to Luke Aldred, University of New England, Australia.  Posted 6/8/06.)

page 361 - Example 11.24 - in the evaluation of the integral, the 1.337841 should be -0.00220.  The final probability is then 94.1%, not 98.1%
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 3/2/05.)

page 373 - Next-to-last paragraph and Figure 12.2 - 1420 MHz is equivalent to a wavelength of 21 cm, not a wavenumber of 21 cm -1.

(Thanks to Dr. Tim Thomas, University of Missouri at Kansas City.  Posted 1/27/04.)

page 408 et seq. - Equation 12.46 is missing a term, and because of that the example that follows (Example 12.14) and the graphing exercise 12.48 are invalid.  I am working on how to best publish a correction prior to the reprinting of the text.
(Thanks to Dr. Timothy Thomas, University of Missouri at Kansas City.  Thanks also to Dr. Matthew Marmorino, Indiana University. Posted 2/23/04. )

(Thanks to Joyce Anderson, Cleveland State University.  Posted 2/16/05.)

page 811 - Answers to Selected Exercises - 13.6.  The matrix for the C2 operation is incorrect.  The first row should read "-1  0  0" and the second row should read "0  -1  0".
(Thanks to Justin Bohn, Cleveland State University.  Thanks also to Amy Mulka of John Carroll University.  Reposted 6/17/05.)

page 812 - Answers to Selected Exercises -  14.12.  The values for A, B, and C are correct in J units, but in cm-1 units they are not (looks like they are cm units, not wavenumber units.)  Take the reciprocal of each numerical value for the correct value in wavenumber units.
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 3/30/05.)

page 814 - Answers to Selected Exercises - 18.6.  Because of the error in Example 18.2, the values of the partition functions are incorrect.  The correct values should be q(5 K) = ~3.000, q(298 K) = 4.143, and q(1000 K) = 5.250.

Errors in the Student Solutions Manual (in numerical order)

#1.13 - The units should all be lb/in2.
(Thanks to Philip Traylor, John Carroll University.  Posted 9/8/04.)

#2.3 - The minus sign, present initially, was inadvertantly dropped.  The correct answer should be -94.4 J.
(Thanks to Joseph Haoui, John Carroll University.  Posted 9/17/03.)

#2.5(d) - The work should be less if it were irreversible, not more.  The amount of work done reversibly is the greatest amount of work that can be done by a process.
(Thanks to Dr. David Ewing, John Carroll University.  Posted 9/16/03.)

#2.45 - In the solution for deltaU, the expression should read "deltaH minus delta(pV)", not "deltaH plus delta(pV)".  However, this typo does not change the final answer for deltaU.
(Thanks to Justin Bohn, Cleveland State University.  Posted 10/10/02.)

#3.21 - Yes, the use of 5/2 R _is_ justified because the step it is used for is, indeed, a constant pressure step.
(Thanks to Brigid Long, John Carroll University.  Posted 10/13/04.)

#4.23(e) - I didn't combine terms and when you do, this is indeed an exact differential.
(Thanks to Dr. Matthew Marmorino, Indiana University.  Posted 10/3/03.)

#4.47(a) - Because it's an equilibrium situation, the chemical potentials of both H2O(l) and H2O(g) should be the same.
(Thanks to Dr. Mary Ellen Scott, Baldwin-Wallace College.  Posted 2/23/04.)

#7.51 - The final answer should be 1104 bar.
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 11/17/04.)

#8.13 - The silver reactions are backwards.  It should be 2Ag + + H2  -->  2Ag + 2H+ and 2Ag + + 2Hg + 2Cl- --> 2Ag + Hg 2 Cl 2 .
(Thanks to Joshua Czerwinski, John Carroll University.  Posted 11/24/03.)

(Thanks to Tommie McSherry, New Mexico Institute of Mining and Technology.  Posted 11/11/03.)

#10.19 - In two integrals, the lower limit is given as 2, instead of 0.  However, the problem is worked out correctly.
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 2/10/05.)

#10.23(d) - It should be (2/a)3 in the denominator of the solved integral, not (1/a)3.  This effectively removes the 8 from the final solution.
(Thanks to Kristen Hudach, John Carroll University.  Posted 2/23/04.)

#10.55 - The third term in the second pair of parentheses should be zero, making the final answer a2/3-a2/4(pi)2.
(Thanks to John DeCoulo, Cleveland State University.  Posted 2/8/07.)

#11.27 - After the second equation in the solution (on the line that starts with 20.7 cm-1), the unit in the expression for I is J2m2/cm-1.  It should be J2s2/cm-1.  However, the problem is solved correctly (final units and all).
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 3/1/05.)

#11.53(e) - The answer should be 1, 4, and 5 nodes, respectively.
(Thanks to Jennifer Wadenpfuhl and Joyce Anderson, Cleveland State University.  Posted 3/16/05.)

#12.15 - Two typos in the symbols of elements that don't follow the aufbau principal:  Pd (not Pb), and Gd (not Gc).
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 3/8/05.)

#12.21 - After fixing several typos in the solution to the integral, the value of a3 comes out to be exactly zero.
(Thanks to Dr. Mark Elert, US Naval Academy.  Posted 3/30/06.)

#13.37 - The orbital should actually have B1u symmetry, not B3u.
(Thanks to Kristin Ewing, Indiana University.  Posted 3/26/04.)

#14.15 - The solutions neglect to consider the K terms where applicable; they should be include to see if they make a difference.
(Thanks to Ryan Richard, Cleveland State University.  Posted 3/23/07.)

#14.35 - The molar mass of oxygen should be 16, not 18.
(Thanks to Ryan Richard, Cleveland State University.  Posted 3/23/07.)

#14.55 - The answer should more properly refer to number of infrared absorptions, rather than vibrations, because some of the vibrations are degenerate and represent more than one vibration.
(Thanks to Dr. Matt Marmorina, Indiana University.  Posted 7/8/04.)

#17.17 - The incorrect number is being used in the final step of the second part.  The numberator should be 5.38x10-22, and the correct final answer should be 76.3 K.
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 4/26/05.)

Errors in the Instructor Solutions Manual (in numerical order)
#2.52:  Answer should be -57.19 kJ.
(Thanks to Dr. Joseph Brom, University of St. Thomas.  Posted 9/19/02.)

#2.58:  The answer used the reactants, not the products, of the reaction.  The correct final answer should be deltaT = 4710 K.
(Thanks to Dr. James Whitten,

#4.16:  The table gives deltaHs for sodium and lithium, not deltaGs.  Apologies.
(Thanks to Dr. Mark Waner, John Carroll University.  Posted 11/24/03.)

#4.20.  The variable being held constant in the numerator should be V, not T.  The numerator should read (dS/d p )V.
(Thanks to Dr. Alyx Frantzen, Stephen F. Austin State University.  Posted 11/21/02.)

#4.50 - The solution should not have the variable n in it, since compressabilities are usually expressed in molar terms (so n = 1 mol).
(Thanks to Dr. Kurt Grafton, Lyon College.  Posted 3/1/05.)

#5.10:  The two terms should be added, not subtracted.  The correct answer would be -539.26 kJ.
(Thanks to Melissa McCulloch, Cleveland State University.  Posted 10/11/02.)

#6.10:  In the last step, the heat capacity used has the wrong unit; it should be per gram, not per mole.  The numberical value for heat is correct, however.
(Thanks to Jennifer Wadenpfuhl, Cleveland State University.  Posted 10/19/04.)

#6.24:  The mega- part of the pressure was dropped.  When included, the correct answer should be 1904 kJ/mol.
(Thanks to Dr. Matthew Marmorino, Indiana University.  Posted 10/20/03.)

#9.22:  The factor of delta-lambda was not included in the final calculation.  The correct answers should be 1.01x10-10 W/m 2 , 8.11x101 W/m2, and 1.19x106 W/m 2 , respectively.
(Thanks to Dr. Lily Ng, Cleveland State University.  Posted 2/6/04.)

#10.46:  Second line on page 47, the second appearance of a3 /(4 pi2) should be replaced with a zero.  This adds an additional term to <x2>, reducing it by about 15%, but the product of the uncertainties is still greater than h-bar/2.
(Thanks to Keri Hershberger, Indiana University.  Posted 2/23/04.)

#10.50 - see error listed on page 810, above.

#16.26(a) - It is more proper to say that the protons in the methyl group are split into "a triplet", rather than "triplets".
(Thanks to Hilda Namanja and Keri Hershberger, Indiana University.  Posted 7/8/04.)

#16.26(b) - Because of cyclobutane's constantly-inverting C4 backbone, all hydrogens experience the same average environment and there is only one NMR absorption.  (I'll change this example in the next edition.)
(Thanks to Hilda Namanja and Keri Hershberger, Indiana University.  Posted 7/8/04.)

#19.8 - Proper rounding to one significant figure should yield 4x1012 K, rather than 3x1012 K.
(Thanks to Dr. Ben Erné, Utrecht University.  Posted 3/30/06.)

#20.18(c) - There should not be a 2 in the denominator of the expression in the numerator.  It should simply be "2 - sqrt(2)".
(Thanks to Kristin Ewing, Indiana University.  Posted 12/2/03.)
