A reaction is experimentally found to follow the rate law, Rate = k[A]² where k = 0.130 M^-1min^-1. Starting with [A]_o = 2.50 M, how many seconds will it take for [A]_t = 1.25 M

To solve this problem, we need to use the integrated rate law for this reaction, ln ([A]_o/[A]_t) = k t Plugging in the given values, we get: ln (2.50/1.25) = (0.130 min^-1-1)(t)^S1S1P12 Simplifying the expression, we get: 0.693 = (0.130 min^-1-1)(t)^S1S1P12 Solving for t, we get: t = (0.693)/(0.130)(2S1S1) = 185 s Therefore, the answer is B.
