This document describes an experiment to investigate the effect of surface area on the rate of a catalyzed reaction using the enzyme catalase. Catalase is an enzyme found in living cells that speeds up the breakdown of hydrogen peroxide into water and oxygen. The experiment will involve measuring the time taken for catalase to breakdown hydrogen peroxide at different surface areas of a catalase solution. Controls and repeated trials will help ensure accuracy and reliability of the results. Factors like temperature will be kept consistent to avoid their confounding effects on the reaction rate.
