In the reaction of 0.200 M gaseous N2O5 to yield NO2 gas and O2 gas as shown below: 2 N2O5 (g) → 4 NO 2 (g) + + O2(g) the following data table is obtained: Time (sec) [N2O5] 0 [02] 0.200 M 0 300 0.180 M 0.010 M 600 0.162 M 0.019 M 900 0.146 M 0.027 M 1200 0.132 M 0.034 M 1800 0.110 M 0.045 M 2400 0.096 M 0.052 M 3000 0.092 M 0.054 M (a) Use the [02] data from the table to calculate the average rate over the measured time interval from 0 to 3000 secs. (b) Use the [02] data from the table to calculate the instantaneous rate early in the reaction (0 secs to 300 sec). (c) Use the [02] 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.
