Question
At 40°C, H2O2 (aq) will decompose according to the following reaction:
2H2 O2 (ag) → 2H, O(1) + O2(g)
The following data were collected for the concentration of H2 O2 at various times.
Time (s) [H2 O2] (mol/L)
1.300
1.69 × 104
0.756
3.38 x 104
0.439
a. Calculate the average rate of decomposition of H2 O2 between 0 and 1.69 x 104 s.
Average rate =
mol/L·s
Use this rate to calculate the average rate of production of O2 (g) over the same time period.
Average rate =
mol/L· s
b. What are these rates for the time period 1.69 × 10ª s to 3.38 × 104 s?
Rate of H2 O2 decomposition
mol/L·s
Rate of O2 production
mol/L · s
