Does the number of moles of reaction products increase, decrease or remain same when each of the following equilibria is subjected to a decrease in pressure by increasing the volume?
(i) PCl5(g) = PCl3(g) + Cl2(g)
(ii) CaO(s) + CO2(g) = CaCO3(s)
(A) (i) increase, (ii) increase
(B) (i) decrease, (ii) decrease
(C) (i) increase, (ii) decrease
(D) (i) decrease, (ii) increase
