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.

Times(s)	[H₂O₂](mol/L)
0	1.000
2.16 x 10⁴	0.500
4.32 x 10⁴	0.250

a. Calculate the average rate of decomposition of H₂O₂ between 0 and 2.16 x 10⁴ s. Use this rate to calculate the average rate of production of O₂(g) over the same time period.

b. What are these rates for the time period 2.16 x 10⁴ s to 4.32 x 10⁴ s?
