Question

All work and answers should be written on your own paper. 1. (6 Pts) Write the equilibrium expression, Kc, for the following reactions. a. 2 SO2(g) + O2(g) = 2 SO3(g) b. Cl(g) + O3(g) = CIO(g) + O2(g) c. 4 KO2() + 2 H2O(g) = 4 KOH(s) + 3 O2(g) 2. (6 Pts) Write the equilibrium expression, Kr, for the reactions in problem 1. 3. (8 Pts) At 127°C, Kc = 2.6 x 10- for the reaction: 2 NH3(g) + N2(g) + 3 H2(g) Calculate Kp at this temperature. 4. (10 Pts) A 1.00-L flask was filled with 2.00 mol gaseous SO, and 2.00 mol gaseous NO, and heated. After equilibrium was reached, it was found that 1.30 mol gaseous NO was present. Assume that the reaction: SO2(g) + NO2(g) =SO(g) + NO(g) occurs under these conditions. Calculate the value of the equilibrium constant, Kc. 5. (12 Pts) At a particular temperature, Kc = 1.00 x 10' for the reaction H2(g) +12(g) + 2 HI(g) In an experiment, 1.00 mol H2, 1.00 mol 12, and 1.00 mol HI are introduced into a 1.00-L container. Calculate the concentrations of all species when equilibrium is reached 6. (12 Pts) In which direction will the position of the equilibrium 2 HI(g) = H2(g) + 12(g) be shifted for each of the following changes? a. Hz(g) is added b. Iz(g) is removed c. HI(g) is removed. d. Some Ar(g) is added. e. The volume of the container is doubled. f. The temperature is decreased. The reaction is exothermic)
