Cooley · Answer 1

Using the 2nd order integrated rate law.

1/A1 = 1/A0 + Kt

A1 = 0.267

A0 = 0.467

k = 1.6

t = time

1/A13 = 1/0.467 + 1.6 (13)

1/A13 = 1/0.467 + 20.8

1/A13 = 2.141 + 20.8

1/A13 = 22.941

1 = 22.941 * A13

1/22.941 = A13

A13 = 0.04359

The concentration of X after 13 minutes is 0.04359
