What is the role of a catalyst in a reversible reactions?

What is the role of a catalyst in a reversible reactions?

Options

  1. AIncrease the rate of forward reaction
  2. BDecrease the rate of backward reaction
  3. CAlter the equilibrium constant of the reaction
  4. DAllow the equilibrium to be achieved quickly

Correct answer

D. Allow the equilibrium to be achieved quickly

Step-by-step solution

An increase in rate of reaction in forward direction by a catalyst for a reaction in equilibrium brings in an increase in concentration of products and thus rate of backward reaction also increase to same magnitude and so allow the equilibrium to be achieved quickly.
