The decomposition of hydrogen peroxide is first order in H2O2. 2H2O2 -----> 2H2O + O2 The rate constant for this reaction at 20 C is 1.8 * 10^-5 s^-1. If the starting concentration of H2O2 is 0.75 M, determine (A) the concentration of H2O2 remaining after 3 hours and (B) How long it will take for the H2O2 concentration to drop to 0.10 M?
