Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific principle?Increase in chemical reaction rate due to a catalyst
2. What is the catalyst characteristic?Catalysts are not consumed by the reaction and remain unchanged
3. How does a catalyst make reactions faster?It lowers the activation energy, which is the energy needed to start the reaction. With less energy needed, the reaction can happen much quicker.
4. Why do factories use catalysts?Catalysts help make many products faster and use less energy. They also reduce waste and help protect the environment.

Catalysis: The process by which a catalyst increases the rate of a chemical reaction.
Catalyst: A substance that accelerates a chemical reaction without being consumed.
Activation Energy: The minimum energy required to initiate a chemical reaction.
Homogeneous Catalysis: Catalysis where the catalyst and reactants are in the same phase.
