3) 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?
