(D) Key Idea: The relationship between $K_p$ and $K_c$ is given by $K_p = K_c(RT)^{\Delta n_g}$,where $\Delta n_g$ is the change in the number of moles of gaseous species.$K_p$ and $K_c$ are not equal when $\Delta n_g \neq 0$.$(a)$ $\Delta n_g = (1+1) - 2 = 0$,so $K_p = K_c$.$(b)$ $\Delta n_g = (1+1) - (1+1) = 0$,so $K_p = K_c$.$(c)$ $\Delta n_g = 2 - (1+1) = 0$,so $K_p = K_c$.$(d)$ $\Delta n_g = 2 - 1 = 1$,so $K_p = K_c(RT)^1$,which means $K_p \neq K_c$.
