(a) Use the [O2] data from the table to calculate the average rate over the
measured time interval from 0 to 3000 secs.

(b) Use the [O2] data from the table to calculate the instantaneous rate
early in the reaction (0 secs to 300 sec).

(c) Use the [O2] data from the table to calculate the instantaneous rate
late in the reaction (2400 secs to 3000 secs).

(d) Explain the relative values of the average rate, early instantaneous
rate and late instantaneous rate.
