  • question_answer
    A chemical reaction is catalysed by catalyst X. Hence, X

    A)  increases the activation energy of reaction.

    B)  does not effect the equilibrium constant of reaction.

    C)  decreases the velocity constant of reaction.

    D)  decreases the enthalpy of reaction.

    Correct Answer: B

    Solution :

     In a chemical reaction, catalyst increases the rate of forward and backward reaction equally hence catalyst does not effect the equilibrium constant of reaction.
