In the reaction of gaseous N2O5 to yieldNO2 gas and O2 gas as shown below thefollowing data table is obtained:
2 N2O5 (g) → 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.
