An experiment to investigate how the rate of enzyme reaction is affected by the pH Aim & Hypothesis/Null Hypothesis The aim of this experiment is to find out whether pH levels affect the working rate of reaction of the enzyme catalase as it breaks down hydrogen peroxide. My prediction (hypothesis) is that the rate of reaction depends on the pH of the environment that the enzyme is placed in. I also predict that the enzyme will have an optimum functioning pH that it works best at (i.e. has the highest rate of reaction at a particular pH level). As the pH level approaches this optimum, the rate of reaction will increase, then peak at the optimum pH, then after this point, the rate of reaction will begin to decrease again (see fig.1 below) My null hypothesis is that the pH level will have no effect on the rate of reaction, and it is...
