For the reaction

2S{O_2}(g) + {O_2}(g) \to 2S{O_3}(g),\Delta H = - 57.2\mathrm{kJ}\,\mathrm{mo}{\mathrm{l}^{ - 1}}\mathrm{ and }{K_c} = 1.7 \times {10^{16}}

Which of the following statement is incorrect?

View answer and explanation

Correct option: D

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

The correct answer is D because a large equilibrium constant suggests the reaction goes to completion, but a catalyst is still needed to increase the rate of reaction.
