How do enzymes affect free energy change?

Answer 1

Enzymes are catalysts, they are not magic.

Free energy change is constant, but catalysts can speed up the process of reaching equilibrium. Catalysts have no effect on the chemical equilibrium and, therefore, the free energy change.

Enzymes lower the activation energy required for a chemical reaction to occur, which increases the rate of the reaction. This decrease in activation energy does not affect the overall free energy change of the reaction. Instead, enzymes facilitate the conversion of reactants into products by stabilizing the transition state, allowing the reaction to proceed more rapidly. As a result, enzymes do not alter the free energy change associated with a reaction, but they accelerate the attainment of equilibrium by facilitating the formation of products.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
