Hydrogen peroxide decomposes to water and oxygen according to the following reaction: H,O: + H0 + % O Its rate of decomposition is measured by titrating samples of the solution with potassium permanganate at certain intervals. 1. Initial rate determinations at 25 C for the decomposition give the following data (H:O:] 0.200 0.300 0.500 Initial rate (mol/L min) 1.03 X 104 1.55 X 104 2.59 X 104 What is the order of the reaction? Write the rate equation for the decomposition. Calculate the rate constant and the half-life for the reaction at 25 C

Follow-up Question
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?
