Step-by-step explanation:
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
