Equilibrium

For the reaction, 2SO₂(g) + O₂(g) $\rightleftharpoons$2SO₃(g), ΔH= -57. 2kJ mol^-1 and K_c = 1.7 × 10⁶. Which of the following statement is INCORRECT ?

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

• The equilibrium constant decreases as the temperature increases.

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

• Volume will not affect the equilibrium constant
