Discussion The purpose of this experiment was to determine the effects of concentration and temperature  on the rate of the catalyzed decomposition of hydrogen peroxide.   In part one of the experiment, the volume of O2 collected and the time it took was used to  calculate the rate law for the decomposition of hydrogen peroxide. Balanced equation:  In this reaction, the order of reactions for [H2O2] as well as [I-] were relatively around one.  To  be exact, the calculated order of reactions for [H2O2] was 1 and [I-] was 1.168.  The overall  order of reactions is therefore 2.168.  This was calculated using the slope; the slope of volume  O2 collected/time (in seconds) to calculate the reaction rate.  The reaction rate was then  compared in a ratio to the concentration change.  This was used to calculate the reaction order  of individual concentrations.
