for the reaction co g cl2 g harpoons cocl2 g the kpkc is

For the reaction, $$CO\left( g \right) + C{l_2}\left( g \right) \rightleftharpoons COC{l_2}\left( g \right)$$ the $$\frac{{{K_p}}}{{{K_c}}}$$ is equal to

A. $$\sqrt {RT} $$

B. RT

C. $$\frac{1}{{RT}}$$

D. 1.0

Answer : $$\frac{1}{{RT}}$$

Solution :
$$\eqalign{ & {K_p} = {K_c}{\left( {RT} \right)^{\Delta n}};\,\,{\text{Here}}\,\Delta n = 1 - 2 = - 1 \cr & \therefore \,\,\frac{{{K_p}}}{{{K_c}}} = \frac{1}{{RT}} \cr} $$
