5. A catalyst is a substance used to increase the rate of a chemical reaction. Two catalysts are tested to see which will most effectively increase the rate of hydrogen peroxide decomposition. Hydrogen
peroxide decomposes into water and oxygen.
HYPOTHESIS: Catalyst A will increase the rate of reaction faster than Catalyst B.
Independent variable:
Dependent variable:
