Hydrogen Peroxide
Rate of Reaction
Kevin Frappier

The reason for conducting this lab is discover is changing hydrogen peroxide (H2O2) concentration will affect the rate of reaction. During the experiment, the H2O2 rate will be changed and pressure will be measured using a gas pressure sensor. The data suggests that as the hydrogen peroxide concentration increases, the rate of diffusion increases and that my hypothesis is valid.

Hydrogen peroxide is a by-product of biochemical metabolism. The accumulation of hydrogen peroxide can be deadly, so it must be decomposed. One of the decomposing factors is an enzyme called Catalase. Catalase breaks hydrogen peroxide into water and oxygen. Since this is a decomposition reaction, it is exothermic. Hydrogen peroxide can gradually degenerate itself, it decomposes much faster with the help of Catalase which lowers the activation energy to the minimum energy barrier that hydrogen peroxide molecules should overcome to decompose.
