Unformatted text preview: 2 (g) 4HI(g) 5. Consider the following reaction: CO(g) + H 2 O(g) H 2 (g) + CO 2 (g) (exothermic) How will the equilibrium position shift in each of the following cases? a. The volume of the container is decreased? b. Water vapor is added. c. The temperature is increased. d. Gaseous carbon dioxide is removed. 6. The K c at 100C is 2.0 for the reaction 2NOBr(g) 2NO(g) + Br 2 (g) In an experiment, 1.0 mole of NO, 1.0 mole of NOBr and 1.0 mole of Br 2 was placed in a 1.0 L container. a. What is the equilibrium constant expression for the reaction? b. Is the system at equilibrium? c. If not, will the rate of the forward or reverse reaction initially speed up? d. Which concentration(s) will be greater than 1.0 mole/L at equilibrium, and which will be less than 1.0 mole/L? 7. What are [Cu 2+ ] and [CO 3 2-] in a saturated CuCO 3 solution if the K sp of CuCO 3 is 1 x 10-26 ?...
