Question 1

A reaction was experimentally determined to follow the rate law, Rate = k[A] where k = 0.15 s^-1. Starting with [A]_o = 0.225M, how many seconds will it take for [A]_t = 0.0350M
◦ 3.4 x 10^-2 s
◦ 5.3 x 10^-3 s
◦ 12 s
◦ 160 s
◦ 1.3 s

Question 2

A reaction was experimentally determined to follow the rate law, Rate = k[A]² where k = 0.456 s^-1M^-1. Starting with [A]_o = 0.500 M, how many seconds will it take for [A]_t = 0.250 M?
◦ 2.85 x 10^-2 s
◦ 1.14 x 10^-1 s
◦ 1.52 s
◦ 4.39 s
◦ 5.48x10^-1 s
