Which among the following is incorrect about equilibrium state?a)Rate ...
Equilibrium State

Equilibrium state is a condition in which the rate of the forward reaction is equal to the rate of the backward reaction. It is a dynamic state, meaning that the forward and backward reactions are still occurring even though their rates are equal. At equilibrium, the concentrations of the reactants and products remain constant.

Incorrect Statement

The statement that catalysts increase the value of equilibrium constant is incorrect. Catalysts do not affect the position of equilibrium or the value of equilibrium constant. They only increase the rate at which the equilibrium is attained.

Explanation

Equilibrium constant (Kc) is a measure of the extent to which a reaction proceeds towards products. It is given by the ratio of the product concentrations to the reactant concentrations, each raised to their respective stoichiometric coefficients. The value of Kc is determined only by the temperature and the stoichiometry of the reaction.

Catalysts, on the other hand, lower the activation energy of the reaction, allowing more reactant molecules to overcome the energy barrier and participate in the reaction. This increases the rate at which the reaction reaches equilibrium, but it does not affect the position of equilibrium or the value of Kc.

Conclusion

In conclusion, the statement that catalysts increase the value of equilibrium constant is incorrect. Catalysts only increase the rate at which equilibrium is attained, but they do not affect the position of equilibrium or the value of equilibrium constant.
