Answer (d) due to : A catalyst increases the rate of a reaction by providing an alternative pathway with lower activation energy.
However, it does not affect the overall thermodynamics of the reaction.
This means:
The free energy change (ΔG) of the reaction remains unchanged.
The equilibrium constant (K) also remains the same.
The enthalpy change (ΔH) and entropy change (ΔS) are unaffected.
Final Answer: neither (a) nor (b).

D is the answer.
Catalyst lowers the activation energy, but it does not change the energies of the original reactants or products, and so no change of free energy.
