Chem 125 Dr. Retsek Winter 2007 Worksheet 6: Equilibrium 1. Write equilibrium constant expressions, K c , for the following reactions: a. 2 NO (g) + O 2 (g) 2 NO 2 (g) b. Zn (s) + 2 Ag + (aq) Zn 2+ (aq) + 2 Ag (s) c. Mg(OH) 2 (s) + CO 3 2- (aq) MgCO 3 (s) + 2 OH - (aq) 2. Write equilibrium constant expressions, K p , for the following reactions: a. CS 2 (g) + 4 H 2 (g) CH 4 (g) + 2 H 2 S (g) b. Ag 2 O (s) 2 Ag (s) + ½ O 2 (g) c. 2 NaHCO 3 (s) Na 2 CO 3 (s) + CO 2 (g) + H 2 O (g) 3. From these values of K c , a. CO (g) + H 2 O (g) CO 2 (g) + H 2 (g) K c = 23.2 at 600 K b. SO 2 (g) + ½ O 2 (g) SO 3 (g) K c = 56 at 900 K c. 2 H 2 S (g) 2 H 2 (g) + S 2 (g) K c = 2.3 x 10 -4 at 1405 K determine values of K c (and K p ) for the following reactions at the temperatures given: a. CO 2 (g) + H 2 (g) CO (g) + H 2 O (g) b. 2 SO 2 (g) + O 2 (g) 2 SO 3 (g) c. H 2 (g) + ½ S 2 (g) H 2 S (g) 4. Equilibrium is established in the reversible reaction 2 A + B
