Vedclass · Answer

(A) The relationship between $K_p$ and $K_c$ is given by the equation $K_p = K_c(RT)^{\Delta n_g}$, where $\Delta n_g$ is the change in the number of moles of gaseous products and reactants.For $K_p = K_c$, the condition is $\Delta n_g = 0$.Let us calculate $\Delta n_g$ for each reaction:$(A)$ $N_2(g) + O_2(g) \rightleftharpoons 2NO(g) \implies \Delta n_g = 2 - (1+1) = 0$.$(B)$ $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) \implies \Delta n_g = 2 - (2+1) = -1$.$(C)$ $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g) \implies \Delta n_g = 2 - (1+3) = -2$.$(D)$ $PCl_5(g) \rightleftharpoons PCl_3(g) + Cl_2(g) \implies \Delta n_g = (1+1) - 1 = 1$.Only reaction $(A)$ satisfies the condition $\Delta n_g = 0$.
