Question:

When a catalyst takes part in a chemical reaction, what is the effect on Gibbs free energy change for the reaction?

Options:

A catalyst alter the Gibbs free energy change for a reaction.

A catalyst does not alter the Gibbs free energy change for a reaction.

A catalyst makes Gibbs free energy of a reaction zero.

None of these

Correct Answer:

A catalyst does not alter the Gibbs free energy change for a reaction.

Explanation:

A small amount of the catalyst can catalyse a large amount of reactants. A catalyst does not alter Gibbs energy, ∆G of a reaction.
