Plan Catalase is an enzyme commonly found in living organism. It speeds up the breakdown of hydrogen peroxide into water and oxygen. The chemical equation for this process is: 2 H2O2 › 2 H2O + O2 + Energy I am going to find out the effect of surface area on the activity (rate of reaction) of the enzyme catalase. I will do this by cutting potato, which contains catalase, into smaller pieces. I will then drop the small pieces of potato into hydrogen peroxide solution and observe how the rate of reaction changes as I am varying the size of the potato. I predict the rate of reaction will be quicker when the potato is in smaller pieces because they give a larger surface area, thus it will increase the collision between the catalase and the hydrogen peroxide. As a result, the rate of reaction will be increased as the small pieces of...
