Consider the reaction 2A ----> B. The following data has been collected during an experiment: Time (s) 0.0 5.0 10.0 15.0 20.0 25.0 35.0 [A] (M) 1.00 0.775 0.625 0.465 0.360 0.285 0.230 Calculate the rate of disappearance of A (average rate of disappearance of A) between 0.0 s and 10.0 s using the definition (change in concentration over time). Then, calculate that again for the time interval 10.0 s to 20.0 s. Are the two rates equal or different?
