Question

Which of the following statements about the catalyst is true?

• A. A catalyst makes the reaction feasible by making $\Delta G$ more negative.
• B. A catalyst makes equilibrium constant more favourable for forward reaction.
• C. A catalyst accelerate rate of reaction by bringing down the activation energy.
• D. A catalyst always increases the rate of reaction.

Answer 1

Answer: (C)

A catalyst is an agent used to accelerate the rate of reaction by decreasing activation energy as activation energy as activation energy is the barrier needed to be crossed by reactants to perform a reaction
