Assuming , for which of the following gaseous equilibrium reactions is ? — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

From $K_p = K_c(RT)^{\Delta n_g}$, for $K_p < K_c$ when $RT > 1$, the exponent $\Delta n_g$ must be negative ($\Delta n_g < 0$). For ammonia synthesis, $\Delta n_g = 2 - 4 = -2$, making $K_p < K_c$.
