Question:

At 40°C, H2O2(aq) will decompose according to the following reaction:

2HO(aq)  2HO(1) + O(g)

The following data were collected for the concentration of H2O2 at various times.

Time (s) 0 2.16 X 104 4.32 X 104 [HO] (mol/L) 1.000 0.500 0.250

a. Calculate the average rate of decomposition of H2O2 between 0 and 2.16 × 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 × 10s to 4.32 × 104 s?
