Explain the difference between the instantaneous rate of a reaction and the average rate of a reaction.


 

The difference between the instantaneous rate of reaction and the average rate of a reaction is as below

 

Instantaneous rate of reaction Average rate of reaction

(i)  It occurs within a short span of time.

(ii) It can't be calculated for multistep rcaction

(iii) It can be calculated for elementary reaction.

 It occurs during a long interval of time.

It can calculated for multistep reaction.

It can be calculated for elementary reaction,
