The following reaction, catalyzed by iridium, is endothermic at 700 k: cao(s) + ch4(g) + 2h2o(g) ⇌ caco3(s) + 4h2(g) for a reaction mixture at equilibrium at 700 k, how would the following changes affect the total quantity of caco3 (increase, decrease, or unchanged) in the reaction mixture once equilibrium is re-established?.
