Chapter 12, Problem 121CP

Consider the hypothetical reaction

A + B +2C 2 D + 3E

In a study of this reaction three experiments were run at the same temperature. The rate is defined as −∆[B]/∆t.

Experiment 1:

[A]0 = 2.0 M      [B]0 = 1.0 × 10−3 M     [C]0 = 1.0 M

[B] (mol/L) Time(s)
2.7 × 10−4 1.0 × 105
1.6 × 10−4 2.0 × 105
1.1 × 10−4 3.0 × 105
8.5 × 10−5 4.0 × 105
6.9 × 10−5 5.0 × 105
5.8 × 10−5 6.0 × 105

Experiment 2:

[A]0 = 1.0 × 10−2M     [B]0 = 3.0 M     [C]0 = 1.0 M

[A] (mol/L) Time(s)
8.9 × 10−3 1.0
7.1 × 10−3 3.0
5.5 × 10−3 5.0
3.8 × 10−3 8.0
2.9 × 10−3 10.0
2.0 × 10−3 13.0

Experiment 3:

[A]0 = 10.0 M     [B]0 = 5.0 M     [C]0 = 5.0 × 10−1M

[C] (mol/L) Time(s)
0.43 1.0 × 10−2
0.36 2.0 × 10−2
0.29 3.0 × 10−2
0.22 4.0 × 10−2
0.15 5.0 × 10−2
0.08 6.0 × 10−2

Write the rate law for this reaction, and calculate the value of the rate constant.
