Research into Influential Factors of Catalytic Decomposition Rate of Hydrogen Peroxide

H2O2 decomposition rate is researched with KI as catalyst,different pH and temperature.The results shows:temperature has more effect on decomposition rate than pH value and KI content.The reaction rate constant increases very quickly with the increase of KI content,and increasing trend index is shown with the increase of temperature and the same catalyst content.It is the largest in the neutral with different pH value.
