Concentration of a reactant 'A' is changed from 0.064 M to 0.016M in 8 minutes, the average rate of the reaction during this interval is

Given, [A]=0.064M−0.016M=0.048M Time=8 minutesAverage rate of the reaction=?Average rate=dcdt Where,dc=Change in concentrationdt = Time taken for the change=0.488=0.006mol/lit/min
