The decomposition of H2O2 to O2 + H2O is first-order in H2O2. A solution originally at
0.600 M H2O2 is found to be 0.075 M after 54 min. What is the half-life for the reaction? Please explain yourself.

http://chemwiki.ucdavis.edu/Physical_Chemistry/Kinetics/Reaction_Rates/First-Order_Reactions iI highly recommend the link above the formula for half life of a first order reaction is: half life = ln(2) /k where k is the rate, I recommend reading that website if you have any questions about the material please ask
