What is the difference between the instantaneous rate of a reaction and the average rate of a reaction? The instantaneous rate is measured over a time period; the average rate used the entire reaction. The average rate is the rate over a time period; the instantaneous rate is the rate at a given time. The average rate is measured from the plot of concentration versus time using a tangent line. The average rate is a more accurate measure of the speed of a reaction than the instantaneous rate. O000

Expert Solution
Step 1

Average 
Instantaneous rate 

To find rate of reaction at any instance of time we determine the instantaneous rate

It is formed when we take the average rate at the smallest time interval of time dt  when approaches zero 

∆t becomes dt 

So instantaneous rate of reaction is rate at a given time while average rate is rate over entire time period
