Chapter 15 1. K c for the reaction HCl(g) + NH 3 (g) NH 4 Cl(s) is A. [] [ ] 3 4 NH HCl Cl NH B. Cl NH NH HCl 4 3 C. 3 NH HCl 1 D. [HCl] [NH 3 ] E. [NH 4 Cl] 2. Consider the following three reactions: 1. H 2 (g) + Cl 2 (g) 2 HCl(g) 2. C(s) + H 2 O(g) CO(g) + H 2 (g) 3. Fe 3 O 4 (s) + 4H 2 (g) 3 Fe(s) + 4H 2 O For which of these would K p = K c ? A. 1 only B. 1 and 2 only C. 1 and 3 only D. 3 only E. 2 and 3 only 3. At 50 ° C, K c = 2.2 × 10 3 for the reaction 3 Fe(s) + 4 H 2 O(g) Fe 3 O 4 (s) + 4 H 2 (g) What is the value of K p at 200 ° C for this reaction?

4. For the following reaction, K p = 1.96 at 700 K. NOCl(g) NO(g) + ½ Cl 2 (g) At this same temperature, K p for the reaction Cl 2 (g) + 2 NO(g) 2 NOCl (g) is A. 1.96 B. 3.85 C. 0.260 D. 0.509 E. None of the above is within 5% of the correct answer. 5. K c for the reaction F 2 (g) + Cl 2 (g) 2 FCl(g) equals 125 at a particular temperature. Suppose a system involving this reaction is already at equilibrium and the concentrations of F 2 and Cl 2 are found to be [F 2 ] = 0.115 M and [Cl 2 ] = 0.221 M. What is the concentration of FCl in the system?
