A catalyst increases the rate of a chemical reaction by providing a lower-energy mechanism for the reaction.When this occurs,which one of the following is not affected?

Question

Quizplus · Accepted Answer

The equilibrium constant is a function of the thermodynamics of the reaction and is not affected by the presence of a catalyst. The activation energy for the forward reaction is lowered by the catalyst, leading to an increase in the reaction rate, while the activation energy for the reverse reaction is not affected, so the equilibrium position remains the same. Additionally, the rate of the reverse reaction may also be increased due to the lower activation energy for the forward reaction, allowing some of the products to be converted back into reactants more easily.
