For the reaction: A → Products (order = n), the theoretical time of completion of reaction is — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Integrated rate law is [A]^(1-n) - [A0]^(1-n) = (n-1)kt. Setting [A] = 0 for completion yields t = [A0]^(1-n) / (K(1-n)) when n < 1. For n ≥ 1, the curve asymptotically approaches zero, meaning completion time is theoretically infinite. Therefore, correct answer is B,D.
