Question

Some measurements of the initial rate of a certain reaction are given in the table below.

Use this information to write a rate law for this reaction, and calculate the value of the rate constant

Some measurements of the initial rate of a certain reaction are given in the table below. N2H2 initial rate of reaction 0.206 M 0.925 M 0.206 M0.176 M 0.980 M0.925 M 0.711 MIs 0.0257 M/s 16.1 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 2 significant digits. Also be sure your answer has the correct unit symbol. ratek 0

Explanation / Answer

Based on the tabular values, the rate expression can be written as

rate = k[N2]2*[H2]2

By using from the first row in the table, you can write as follows.

0.711 M/s = k * (0.206 M)2 * (0.925 M)2

i.e. K = 19.582 ~ 20 M-2 s-1
