Question

Which statement describes a reaction at equilibrium

Answer 1

Answer:

The rate of formation of the products must equal the rate of formation of the reactants.

Explanation:

For any chemical reaction to be at equilibrium, the rate of formation of the products must equal the rate of formation of the reactants such that at equilibrium, their mass remains constant.

Answer 2

Option (b)-The entropy of the reactant must be equal to the entropy of the product.

Explanation:

• In a chemical reaction to be in equilibrium, the rate of formation of the products must be equal to the rate of formation of reactants and the mass remains constant.
• The chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal.
• Equilibrium will result in no change in the concentrations of reactants and products.
• The rate of reaction of the formation of products is equal to the rate of formation of reactant.
• At the point of equilibrium, the forward and reverse reaction rates are equal.
