"Enzymes help to achieve the equilibrium faster but cannot changethe thermodynamic
equilibrium constant. Why?"

Answers

Equilibrium constant Kc is defined as the concentration of products over reactants raised to the the powers of its respective molar ratios in of the balanced chemical reaction.
A catalyst by definition is a compound able to catalyse a reaction while being chemically unchanged in the process. The catalyst works by lowering the activation energy by providing an alternative pathway of lower activation energy.
The is no value in the equation whereby activation energy will affect the equilibrium constant.
To know the speed where the reaction reaches equilibrium we need to look at the rate equation also known as Arrhenius equation,
K= Ae^(-Ea/RT)
Here we can see with the lowering of Ea ( activation energy ) the rate constant rises causing the reaction to reach equilibrium quicker.

Final answer:

Enzymes cannot change the thermodynamic equilibrium constant of a reaction because they do not alter the free energy difference between the reactants and products.

Explanation:

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur. They achieve this by providing an alternative reaction pathway with a lower activation energy. However, enzymes cannot change the thermodynamic equilibrium constant of a reaction.

The thermodynamic equilibrium constant is a measure of the ratio of products to reactants at equilibrium. It is determined by the difference in free energy between the reactants and products. Enzymes, although they accelerate the rate at which equilibrium is reached, do not alter the free energy difference between the reactants and products. Therefore, they cannot change the equilibrium constant.
