Integrated Rate Law

Q. The acid-catalyzed decomposition of hydrogen peroxide is a first order reaction. An experiment is run (at 66°C) in which the initial concentration of hydrogen peroxide is 0.110 M. After 254 minutes the concentration of H2O2 remaining is 0.035 M. Overall reaction: 2H2O2 (aq) - > 2H2O (l) + O2 (g) b. what is the half-life at this temperature?
