In the reaction A → products, at t = 0, [A] = 0.1565 M. After 1.00 minute, [A] = 0.1498 M and after 2.00 minutes, [A] = 0.1433. (a) calculate the average rate of the reaction during the first minute

  

In the reaction A → products, at t = 0, [A] = 0.1565 M. After 1.00 minute, [A] = 0.1498 M and after 2.00  minutes, [A] = 0.1433. (a) calculate the average rate of the reaction during the first minute and then during  the second minute. (b) why are these two rates not equal?
