Question
Some measurements of the initial rate of a certain reaction are given in the table below.
[H]
12| initial rate of reaction
1.23M | 1.18М
4.00 × 10°M/s
0.381M 1.18M
1.24 x 10°M/s
1.23M | 3.10м
1.05 x 10°M/s
Use this information to write a rate law for this reaction, and calculate the value of the rate constant k.
Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol.
rate = k |||
