How do catalysts affect a chemical reaction?

Question

1. Provide activation energy.
2. Increase activation energy.
3. Lower activation energy.
4. Lose activation energy. ** I would say LOWER ACTIVATION ENERGY**

Answer 1

You are correct! The correct answer is:

3. Lower activation energy.

Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. They do this by providing an alternative reaction pathway with a lower activation energy, making it easier for the reactants to convert into products. This means that more molecules have enough energy to react, thus speeding up the reaction.
