Calcium oxide is used to remove the pollutant SO2 from smokestack gases by the following exothermic reaction: 2 CaO (s) + 2 SO2 (g) + O2 (g) → CaSO4 (s) If the system was at equilibrium, what effect would each of the following have on the system. For your answer, indicate whether the reaction shifts to the left, shifts to the right, or no change to reestablish equilibrium. a. The concentration of SO2 is decreased. b. Additional CaO is added to the system. c. The volume of the container the reaction is placed in decreases. d. The container that contains the reaction is heated in a hot water bath.
