Chapter 15

- pg 585-6, next to last equation above ‘Substituting...’ on 593 the parentheses are misplaced and Eqn. 15.34 the placement of the last term in brackets may be confusing. The ln applies to only the term including [(1+(1+sqrt(2))bρ)/(1+(1-sqrt(2))bρ)] or the analogous expression with Z and B. Also, on pg 585, eliminate the leading ( and the mating ). (12/30/15)

Chapter 17

- pg 633, at end of first paragraph, "state if aggregation" should be "state of aggregation." (5/9/12)
- pg 635, First line of the paragraph
**Basis**. 'Note the excess hydrogen at the feed conditions' should be 'Note the excess**CO**at the feed conditions'. (10/5/12) - pg 642, middle of first paragraph under "nonstoichiometric feed," it says "repeat example 17.1 with stoichiometric feed (1 mol
**CO2**and 2 mole H2)" where it should be "repeat example 17.1 with stoichiometric feed (1 mol**CO**and 2 mole H2)". The conversion for stoichiometric feed should be 40.6%. This reaction also includes an important pressure effect, and the discussion has been modified. Click here. (5/14/12) - pg 648, Section 17.9 first paragraph, 4th line. Exothermic reactions have a
~~negative~~positive slope and endothermic reactions have a~~positive~~negative slope. (6/1/16) - pg 649, Fig. 17.2, the y-axis should be lnK instead of log

- pg 657-8. The energy balance should have used T
_{R}= 600K for the heat capacity integrals because the ΔH^{o}used this T_{R}. The discussion and results have been updated and the shortcut agrees well with the detailed van't Hoff. Updated pages are available. Click here. (4/17/12) - pg 663, Eqn. 17.64. The term with partial pressures should be multiplied by RT. The exponent of the last term should have a minus preceeding the summation. (4/17/12)
- pg 666, Example 17.12, last line of the equation, 1/3 of the way down the page, insert the term for H2O before the equals sign, "+ 10ln(0.9009*1)". Also, the y-axis on the plot should be
*G*/*RT*. (4/29/12) - pg 680, problem 17.12, second reaction, stoichiometric coefficient for O
_{2}, 5/3 should be 5/2. (12/5/18) - pg 682, problem 17.23(d). Replace T

_{n}. (7/6/13)

Chapter 18

- pg 698, Table 18.2, footnote (a), In both instances where [HCO
_{3}^{-}] appears, it should be multiplied by [H^{+}], e.g. it should appear as [HCO_{3}^{-}][H^{+}]. (4/21/12) - pg 708, first line, 'with' should be 'without'. (4/12/12)
- pg 710, five lines below Eqn. 18.59, change wording to become "
**On**~~From~~the right-hand side, the term 5E-3~~on the left side~~dominates at~~all~~pH < 6. Solutions at high pH are impossible because the decreasing~~right~~**left**-hand side is too small to balance the value of 5E-3 plus increasing concentrations of the negative phosphate**and hydroxide**ions in the~~balance~~**proton conditon**. Therefore, the solution must be at low pH where the concentraion of negative phosphate**and hydroxide ions**in the**proton condition are**~~balance is~~small. "(10/7/12) - pg 718, Example 18.8, last two lines should read "thus the total solubility is
**2**.94(0.018) = 0.0**529**mol/L, or 0.0**529**(306.27) =**16.2**g/L." (4/29/12) - pg 740-1. The variable P
_{i}in the last equation of pg 740 and on the first line of pg 741 and the subscripts in the last equation of the example for ΔG, represents the total of ATP in all forms. In future printings, P_{i}will be replaced by*C*except in the equation for ΔG it will be replaced by ATP. (12/31/12) - pg 746, Eq 18.140, RT is missing in front of the ln() term. Compare to Eq. 18.136. (12/3/18)pg 754, problem 18.8, In the fourth and subsequent printings, the concentrations of sodium and total acetate are changed to 0.05M. This is because the original statement did not have enough carbon to saturate the solution at the partial pressure given. (12/11/12)
- pg 753, problem 18.1. Part (b), calculate at 760 mmHg, part (c) calculate at 25
^{o}C.(12/31/12) - pg 754, problem 18.8. the problem has insufficient carbon to saturate the solution at the specified partal pressure. Revise the amounts of solutes in the second sentence, "The amount of sodium carbonat is such that the total sodium concentration is
**0.05**m and the total acetate concentration is**0.05**m. (12/31/12) - pg 755, equation 18.175 should have exponent 'y' on [H
^{+}], as in [H^{+}]^{y}. In part (d), the values of Q should be Q_{11}and the statement is thus revised to ask: (d) For Fe^{2+}, log Q_{11}= –9.5, and for Ni^{2+}, logQ_{11}= –10.5 and the hydrolyzed ion is soluble for each. Repeat (a) for these ions but relate pH to the ratio of ion concentrations. (7/3/14) - pg 755, problem 18.12(a), last line, the primary alcohol should have a methylene, e.g. "(ketone), -C
**H2**OH(alcohol), -CH2-, -CH3, CH4". (12/31/12) - pg 757, problem 18.15(a) should ask to derive Eqn.
**18.90**, not 18.50. (12/31/12) - pg 757, problem 18.19, should be at 25
^{o}C.(12/31/12)

Chapter 19

- pg 766, improve wording. First, in reference to systems that can only solvate (not associate), the observed activity coefficients of
**A**must be less than one because x_{AM}< x^{o}_{AM}x_{A}when B is present. Second, for systems in which~~one~~component**A**associates and**B**~~the other~~can neither associate nor solvate, the observed activity coefficients**for A**must be greater than one because x_{AM}> x^{o}_{AM}x_{A}when B is present owing to the interference of B with A from dilution. - pg 769, Eqn. 19.25, first two terms should be x_A*x_(BM) - x_B*x_(AM) + ... (12/30/15)
- pg 769, Eqn. 19.28, first two terms should be y_A*y_(BM) - y_B*y_(AM) + ... (12/30/15)
- pg 772, Eqn. 19.33, the leading terms should be x_A*x_(BM) - x_B*x_(AM) + ... (12/30/15)
- pg 772, Eqn. 19.36, the leading terms should be y_A*y_(BM) - y_B*y_(AM) + ... (12/30/15)
- pg 775, Eqns. 19.41-43, where P appears, it is more clear to write P/P
^{o}. (2/4/16) - pg 775-6, add carets to all phi. Two different phi symbols were inadvertently used and should be the same. Eqn 19.42 insert 2 on last two equalities. Eqn 19.45, for the term with the summation, the denominator should be RT. (7/24/14)
- pg 776, Eqn. 19.46 is more clear if each denominator includes P
^{o}. (2/4/16) - pg 777, Eqn. 19.49, left side should be K
_{a}RT/P^{o}. In the line immediately below, K^{C}= K_{ac}RT_{c}/P^{o}and ε/k = ΔH_{Tc}/R. (2/4/16) - pg 777, line below Eqn. 19.51, G
^{assoc}should be G. (10/5/12).^{chem} - pg 780, Figure 19.8, lower left box, replace α with Δ three times. Then replace Delta with 2*Delta five times: box in lower left of figure 19.8 (2x in equation for x_M), Example 19.4, lines 1 and 4. (12/30/15)
- pg 781, Eqn. 19.71 replace K with Δ. (12/29/15)
- pg 782, Eqn. 19.75, for solving for X
^{A}_{i}, this is rearranged, X^{A}_{i}= 1/(1 + Σ_{j}x_{j}N_{d,j}X^{D}_{j}Δ_{ij}^{AD}). The sum is over interacting donor sites, xj is the apparent mole fraction of the site host. Analogous equations are written for the donors where the summation is over interacting acceptor sites.(12/29/15) - pg 783, the sum is over sites and the xi are the apparent molecular mole fraction of the site host. For clarity, each of the three terms of the form ln(X_i^B) + (1-X_i^B)/2 should have brackets surrounding. (12/30/15)
- pg 784, two lines above Eqn. 19.78, in the equation with K
_{a}, replace P with P/P^{o}. (2/4/16) - pg 784, above Eqn. 19.78, should say, For molecules with one donor and one acceptor site, the fraction of unbonded acceptors is the joint probability that the acceptors and donors are both unbonded, and since by mass balance X
^{A}= X^{D}, then n_{M}/n_{o}= X^{A}X^{D}= (X^{A})^{2}= (n_{M}/n_{T})(n_{T}/n_{o}) = x_{M}(n_{T}/n_{o}). We can write the equilibrium relation for i-mer formation using 19.43 as (x_{i}/(x_{M}x_{i-1}) = ((ϕ_{M}ϕ_{i-1})/(ϕ_{i}P^{o}))PK_{a,i}= (Δ)(n_{T}/n_{o}). Combining the probability and equilibrium relations, x_{i}= x_{i-1}(X^{A})^{2}Δ. A recursive relation results, x_{i}= x_{M}((X^{A})^{2}Δ)^{i-1};. Now consider the balances (2/4/16) - pg 784, the equation after Eqn. 19.78 should be n
