Question
At 40°C, H₂O₂ (aq) will decompose according to the following reaction:
2H₂O₂ (aq) → 2H₂O(l) + O₂(g)
The following data were collected for the concentration of H₂O2 at various times.
Time (s) [H₂O₂] (mol/L)
0
2.45 x 10¹
4.90 x 10¹
1.000
0.456
0.208
a. Calculate the average rate of decomposition of H₂O₂ between 0 and 2.45 x 10¹ 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 2.45 x 10¹ s to 4.90 × 10¹ s?
