Combining Ideas

A reaction has the overall stoichiometry of:

A + 2 B → 2 C



A series of experiments were run using the initial rate method in an effort to determine the rate law for this reaction. The data table for these experiments appears below:
Experiment Initial Concentrations (M) Initial Rate
(M/min)
[A] [B]
1 0.434 0.0420 1.91  10-5
2 0.434 0.107 1.24  10-4
1 1.78 0.107 5.10  10-4

What is the value of k for this reaction?

Answer #1

Using experimental data

Rate law,

Rate =k[B]2[A]

k=1.91×10-5 /(0.434)(0.0420)2

k =0.0249 M​​​​​​-2​​min​-1
