Hydrogen peroxide decomposes to water and oxygen according to the reaction below:

2 H2O2(aq) → 2 H2O(l) + O2(g)

In the presence of large excesses of I- ion, the following set of data is obtained. What is the average rate of disappearance of H2O2(aq) in M/s in the first 45.0 seconds of the reaction if 1.00 L of H2O2 reacts at 25°C and 1.00 atm pressure?
