This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis, helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide, which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase, but it would happen a lot more slowly because more energy is needed for the reaction.
This lab demonstrates the effect the enzyme catalase has on the rate of the decomposition reaction of hydrogen peroxide into water and oxygen gas. It would be expected
