(C) The relationship between $K_p$ and $K_c$ is given by $K_p = K_c(RT)^{\Delta n_g}$,so $\frac{K_p}{K_c} = (RT)^{\Delta n_g}$.For $X: \Delta n_g = 2 - (2 + 1) = -1$. Thus,$\frac{K_p}{K_c} = (RT)^{-1} = \frac{1}{RT}$.For $Y: \Delta n_g = (1 + 1) - 1 = 1$. Thus,$\frac{K_p}{K_c} = (RT)^1 = RT$.For $Z: \Delta n_g = (1 + 1) - 2 = 0$. Thus,$\frac{K_p}{K_c} = (RT)^0 = 1$.Since $T = 300 \ K$ $(RT > 1)$,the values are $\frac{1}{RT} Therefore,the increasing order is $X < Z < Y$.
