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?
