Match the following (Reactions vs Unit of rate constant, K) — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Reactions (A) and (C) are first-order reactions, so the unit of their rate constant is time^-1 (P, Q). Reactions (B) and (D) are second-order overall, so the unit of their rate constant is L mol^-1 time^-1 (R, S). Therefore, correct answer is A-P,Q, B-R,S, C-P,Q, D-R,S.
