A reaction is experimentally found to follow the rate law, Rate = k[A]² where k = 0.355 M^-1min^-1. Starting with [A]_o = 1.55 M, how many seconds will it take for [A]_t = 0.150M

Question

Quizplus · Accepted Answer

This is a second-order reaction. The integrated rate law for a second-order reaction is 1/[A]_t = kt + 1/[A]_o. Plugging in the values: 1/0.150 = 0.355 * t + 1/1.55, solving for t gives approximately 1020 seconds.
