Question

The following reaction, catalyzed by iridium, is endothermic at 700 K: CaO (s) + CH4 (g) + 2 H2O (g) CaCO3 (s) + 4 H2 (g)For the reaction mixture above at equilibrium at 700 K, how would the following changes affect the total quantity of CaCO3 in the reaction mixture once equilibrium is re-established? a.) Increasing the temperatureb.) Adding calcium oxide (CaO)c.) Removing methane (CH4)d.) Increasing the total volumee.) Adding iridium
