Chemistry

In the reaction of gaseous N₂O₅ to yieldNO₂ gas and O₂ gas as shown below thefollowing data table is obtained:
2 N₂O₅ (g) â†’ 4 NO₂ (g) +O₂ (g)
Data Table #1
Time (sec)
[N₂O₅] [O₂]
0 0.200 M 0
300 0.182 M 0.009 M
600 0.166 M 0.017 M
900 0.152 M 0.024 M
1200 0.140 M 0.030 M
1800 0.122 M 0.039 M
2400 0.112 M 0.044 M
3000 0.108 M 0.046 M

Complete the following three problems:
Using the [O₂] data from the table show thecalculation of the average rate over the measured time intervalfrom 0 to 3000 secs.
Using the [O₂] data from the table show thecalculation of the instantaneous rate late in the reaction (2400secs to 3000 secs).
Explain the relative values of the average rate and the lateinstantaneous rate.
