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?
