# Errata for Instructors Manual

## US Edition (1st printing)

(2.08), (2.09) - The values for the Cp contants in the table are for Cp/R. The calculated values for H are correct.

(5.13),(5.14) - The solutions are switched.

(6.08) - (a) Method 1: add +R to the RHS of the first derivative. Method 2: add RV2/(V-b) to the RHS of the first derivative. For both methods, correct the remaining algebra. (b) replace (dV/dT)_p with T(dV/dT)_p.

(7.05) - the extra plots on the left side should be ignored.

(8.09) - P2 is 5x too large, so (H-Hig)2 is also 5x too large. Add 8000 to the given ΔH.

(8.15) (c) last line, each numerical value should be negative.

(10.04) - The temperatures are out of range for the Antoine coefficients. The shortcut Psat equation may give more accurate results.

(11.06) - (a),(b) The solution is for 50C. The answers at 30C, for (a), multiply the given P by 0.436. Multiply the given y1 by 1.065; for (b) multiply the given P by 0.416. Multiply the given x1 by 0.863.

(11.16) (c) The value of A12 is wrong, multiply the given value by 1.667. The remainder of the calculations use the correct value for A12.

(12.01) (d) multiply the given A12 by 1.605, multiply A21 by 0.8174. At x1 = 0.1, multiply g1 by 3.76, muliply g2 by 1.013. Multiply given P by 1.245.

(14.20) - volumes were reversed in the US 1st-3rd and 1st INT printing. The values in the solution are fine. The note about which printings have the reversed values is wrong.

(15.15) - The calculations in the solution manual use small kij values and student solutions will be slightly different.

(18.03) - [F-] should not appear in the proton condition, changing the balance. Add about 3.7 to the given pH.

## International Edition (1st printing)

(2.06) - The values for the Cp contants in the table are for Cp/R. The calculated values for H are correct.
