Which of the following analytical expressions correctly relate the different forms of equilibrium co — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

Standard relations are $K_p = K_x P^{\Delta n_g}$ (B) and $K_p = K_c (RT)^{\Delta n_g}$ (A). Equating these gives $K_c (RT)^{\Delta n_g} = K_x P^{\Delta n_g}$, which rearranges to $K_c = K_x (P/RT)^{\Delta n_g}$ (C). Option D is algebraically incorrect; it should be $K_x = K_p(P)^{-\Delta n_g}$.
