Options:

Correct Answer: Decreases activation energy

Solution:

A catalyst lowers the activation energy of a reaction, allowing it to proceed more quickly.

What is the effect of a catalyst on the activation energy of a reaction?

What is the effect of a catalyst on the activation energy of a reaction?

Step 1: Understand what activation energy is. It is the energy needed for a chemical reaction to start.
Step 2: Know what a catalyst is. A catalyst is a substance that speeds up a reaction without being consumed in the process.
Step 3: Learn how a catalyst works. It provides an alternative pathway for the reaction that requires less energy.
Step 4: Realize the effect of a catalyst. By lowering the activation energy, a catalyst allows the reaction to happen faster.
