Question

How does catalyst affect activation energy?


Open in App
Solution

Catalyst:

  • A catalyst is a substance that can be added to a reaction to increasing the reaction rate without getting consumed in the process.
  • Catalysts typically speed up the reaction by lowering the activation energy for both forward and backward reactions.
  • Catalyst provides an alternative pathway with lower activation energy to carry out the reaction which leads to an increase in the rate of reaction.

Therefore, Catalysts generally lower the rate of the reaction.
