Question: What is the role of a catalyst in a chemical reaction?

Options:

  1. It increases the activation energy
  2. It decreases the activation energy
  3. It is consumed in the reaction
  4. It changes the equilibrium position

Correct Answer: It decreases the activation energy

Solution: 

A catalyst lowers the activation energy, allowing the reaction to proceed faster without being consumed.

Questions & Step-by-Step Solutions

What is the role of a catalyst in a chemical reaction?
  • Step 1: Understand that a chemical reaction needs energy to start. This energy is called activation energy.
  • Step 2: A catalyst is a substance that helps the reaction happen more easily.
  • Step 3: The catalyst lowers the activation energy needed for the reaction.
  • Step 4: Because the activation energy is lower, the reaction can happen faster.
  • Step 5: The catalyst is not used up in the reaction, so it can be used again.
