Question

For the reaction,
2SO₂(g) + O₂(g) = 2SO₃(g), $\Delta $H = –57.2 kJ mol^–1 and K_C = 1.7 × 10¹⁶
Which of the following statement is incorrect ?

The equilibrium will shift in forward direction as the pressure increase.

The addition of inert gas at constant volume will be not affect the equilibrium constant.

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

The equilibrium constant decreases as the temperature increase.
