Research question: Which of manganese (IV) oxide and catalase is more effective as a catalyst at lowering the activation
energy for the decomposition of hydrogen peroxide?
Background Information
Hydrogen peroxide
Hydrogen peroxide is a colorless liquid widely used as a disinfectant and a bleaching agent (Jrank). It is unstable and hence
can be decomposed into water and oxygen gas as shown below:
Hydrogen peroxide slowly decomposes in the presence of light and at room temperature, however when a catalyst is involved
in the reaction, the rate of decomposition reaction speeds up (Jrank). One industrial use of hydrogen peroxide is that
electricity can be produced in the fuel cell decomposing hydrogen peroxide (Hasegawa). Hence, if we know which catalyst is
the best at speeding up the rate of reaction, electricity can be produced more rapidly using that catalyst, which makes this
investigation valuable.
