In the first 22.0 s of this reaction, the concentration of HBr dropped from 0.590 M to 0.465 M . Calculate the average rate of the reaction in this time interval.

This is an incomplete question, here is a complete question.

Consider the following reaction:

In the first 22.0 s of this reaction, the concentration of HBr dropped from 0.590 M to 0.465 M . Calculate the average rate of the reaction in this time interval.

Answer : The average rate of reaction is,

Explanation :

The given chemical reaction follows:

The average rate of the reaction for disappearance of HBr is given as:

where,

= final concentration of HBr = 0.465 M

= initial concentration of HBr = 0.590 M

= change in time = 22.0 s

Putting values in above equation, we get:

Hence, the average rate of reaction is,
