Questions & Step-by-Step Solutions

Which of the following statements is true regarding catalysts?
  • Step 1: Understand what a catalyst is. A catalyst is a substance that speeds up a chemical reaction.
  • Step 2: Learn about activation energy. Activation energy is the energy needed to start a reaction.
  • Step 3: Know that catalysts lower the activation energy. This means that reactions can happen more easily and quickly.
  • Step 4: Realize that catalysts are not consumed in the reaction. They can be used over and over again.
  • Step 5: Conclude that because catalysts lower activation energy, they increase the reaction rate.
