For a gaseous reaction: A + B → 2C, the rate law is r = k[A]⁻¹[B]². The incorrect information is — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Rate ∝ [B]²/[A]. With excess A, pseudo-order in B is 2 so t_1/2 ∝ 1/[B] (changes); with excess B, pseudo-order in A is −1 so t_1/2 ∝ [A] (changes). Thus (a) and (c) are incorrect.
