Biology Coursework Investigating the factors that affect the action of catalase (enzyme) on hydrogen peroxide Daniel victory 11BY Analysing From both my tables of results and my graphs we can see that my results match my predictions that the larger the surface area of the potato, the faster the rate of reaction will be and that as more time passed the rate of reaction decreased. So I can say that the surface area of the potato is proportional to rate of reaction and that time is inversely proportional to rate of reaction. I think that as the surface area of the potato increased, the rate of reaction also increased because there was more catalase molecules involved in the reaction and the hydrogen peroxide molecules also had more area to react with the catalase and therefore there were more collisions between molecules and therefore the 'lock and key' mechanisms were taking place faster....
