Question: For the reaction, 2SO 2(g) + O 2(g) ? 2SO 3(g) , ? H = -57.2 kJ mol 1 and Kc = 1.7 10

For the reaction, 2SO2(g) + O2(g) ? 2SO3(g), ?H = -57.2 kJ mol–1 and Kc = 1.7 × 1016 Which of the following statements is incorrect?

(a) The equilibrium will shift in the forward direction as the pressure increases.

(b) The addition of inert gas at constant volume will not affect the equilibrium constant.

(c) The equilibrium constant is large, suggestive of reaction going to completion and so no catalyst is required.

(d) The equilibrium constant decreases as the temperature increases.
