Match the half-life in Column I with the order in Column II for the reaction: A → Products. where a — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The general relationship for half-life is t_1/2 ∝ a^(1-n). (A) Independent of 'a' implies n=1 (First order). (B) Proportional to 'a' implies n=0 (Zero order). (C) Proportional to 1/a implies n=2 (Second order). (D) Proportional to 1/a^2 implies n=3 (Third order). Therefore, correct answer is A-P, B-S, C-R, D-Q.
