Answer:

Explanation:

The enthalpy value will not be affected by a catalyst. A catalyst will only lower the required activation energy for the reactions. Since it will lower the activation energy for both the forward and reverse reactions, the net change in enthalpy is zero.

As said, a catalyst will not change the enthalpy of a reaction.
