A chemical reaction is catalyzed by a catalyst X. Hence X
  • a)
    reduces enthalpy of the reaction
  • b)
    decreases rate constant of reaction
  • c)
    increases activation energy of the reaction
  • d)
    does not affect equilibrium constant of the reaction
Correct answer is option 'D'. Can you explain this answer?

Explanation:

Effect of catalyst X on the reaction:
- A catalyst increases the rate of a chemical reaction by providing an alternate pathway with lower activation energy, without being consumed in the reaction itself.
- The catalyst X does not alter the equilibrium constant of the reaction. It only speeds up the forward and backward reactions equally, leading to a faster attainment of equilibrium.
- Since the equilibrium constant remains unchanged, the enthalpy of the reaction (heat change) is also unaffected by the catalyst X.
- The rate constant of the reaction is increased by the catalyst X as it lowers the activation energy barrier for the reaction to occur.
- By lowering the activation energy, the catalyst X makes it easier for the reactant molecules to overcome the energy barrier and form the products.
Therefore, the correct answer is option 'D' - catalyst X does not affect the equilibrium constant of the reaction.
