CHM 2047 Homework 10 This assignment is due Monday, Nov. 14, in class. 1. Kotz, Ch. 16, Problem 38. 2. Kotz, Ch. 16, Problem 40. 3. Kotz, Ch. 16, Problem 54. 4. Kotz, Ch. 16, Problem 60. 5. Kotz, Ch. 16, Problem 68. 6. Acetic acid in the vapor phase consists of both monomeric and dimeric forms in equi- librium: 2 CH 3 COOH(g) * ) (CH 3 COOH) 2 (g) At 110 C the equilibrium constant for this reaction is 3.72. (a) Calculate the partial pressure of the dimer when the total pressure is 100 atm at equilibrium. (b) What percentage of the acetic acid is dimerized under these conditions? 7. The equilibrium constant for the reduction of nickel(II) oxide to nickel at 754 C is 255.4, corresponding to the reaction NiO(s) + CO(g) * ) Ni(s) + CO 2 (g). If the total pressure of the system at 754 C is 2.50 atm, calculate the partial pressures of CO(g) and CO 2 (g). 8. At 25 C the partition coeFcient for the equilibrium I 2 (aq) * ) I 2 (CCl 4 ) has the value K = 85. To 0.100 L of an aqueous solution, which is initially 2
