At 40oC, H2O2 will decompose according to the following reaction:
2 H2O2 (aq) --> 2 H2O (l) + O2 (g)
The following data were collected for the concentration of H2O2 at various times.
| Time(s) | [H2O2] (mol/L) |
| 0 | 1.000 |
| 2.09 x104 | 0.500 |
| 4.18 x104 | 0.250 |
a) Calculate the average rate of decomposition of H2O2 between 0 and 2.09 x104 seconds. M/s
Use this rate to calculate the average rate of production of O2 over the same time period. M/s
b) What are these rates for the time period 2.09 x104 sec to 4.18 x104 sec.
M/s H2O2
M/s O2
