Question 1

A sealed container holds the following equilibrium system at 500 K: $$2\text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{SO}_3(g) \quad \Delta H = -198 \text{ kJ mol}^{-1}$$ Which change will shift the position of equilibrium to the right (towards products) without changing the value of the equilibrium constant?
