The decomposition of hydrogen peroxide is a first-order reaction: H2O2(aq) → H2O(l) + 1/2 O2(g). The half-life of the reaction is 17.0 minutes.
a. What is the rate constant of the reaction?
b. If you had a bottle of H2O2, how long would it take for 86.0% to decompose?
c. If you started the reaction with [H2O2] = 0.100 M, what would be the hydrogen peroxide concentration after 15.0 minutes?
