Question

In a vessel containing SO3, SO2 and O2 at equilibrium, some helium gas is introduced so that the total pressure increases while temperature and volume remains constant. According to Le-Chatelier principle, the dissociation of SO3 (A) increases (B) decreases (C) remains unaltered (D) changes unpredictably

2 SO3 leftharpoons 2SO2 +O2 Δ H = + v e endothermic reaction Inert gas doesn’t show reaction with the reacting mixture it shows effect only due to its volume. At constant volume the change doesn’t effect the inert gas. Thus dissociation of SO3 remains unchanged. V= constant = Δ n = 0 No effect on the inert gas.
