What is the ratio of rate constant of backward to forward direction? — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

The ratio of the backward rate constant (k_b) to the forward rate constant (k_f) is the inverse of the equilibrium constant K. Ratio = k_b / k_f = 1 / K. Since K = e¹⁰ (from the previous sub-question), the ratio is 1 / e¹⁰ = e⁻¹⁰. Therefore, correct answer is D.
