CHAPTER 13 MAKE UP HOMEWORK 1. Write an expression for the equilibrium constant of each of the following chemical equations. a. SbCl 5 (g) ↔ SbCl 3 (g) + Cl 2 (g) b. 2 BrNO (g) ↔ 2 NO (g) + Br 2 (g) c. CH 4 (g) + 2 H 2 S (g) ↔ CS 2 (g) + 4 H 2 (g) d. 2 CO (g) + O 2 (g) ↔ 2 CO 2 (g) 2. Consider the following reaction: CO (g) + 2 H 2 (g) ↔ CH 3 OH (g) . An equilibrium mixture of this reaction at a certain temperature was found to have [CO] = 0.105 M, [H 2 ] = 0.114 M, and [CH 3 OH] = 0.185 M. What is the value of the equilibrium constant at this temperature? 3. Consider the following reaction: N 2 (g) + 3 H 2 (g) ↔ 2 NH 3 (g) . Complete the following table. Assume that all concentrations are equilibrium concentrations in M. T (K) [N 2 ] [H 2 ] [NH 3 ] K 500 0.115 0.105 0.439 575 0.110 0.128 9.6 775 0.120 0.140 0.0584 4. Consider the reaction: NH 4 HS (s) ↔ NH 3 (g) + H 2 S (g) . At a certain temperature, K = 8.5 x 10 -3 . A reaction mixture at this temperature containing solid NH
