Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate
