Question

Which of the following factors are equal in a reversible chemical reaction at equilibrium?

• A. The number of moles of the reactants and products
• B. The potential energies of the reactants and products
• C. The activation energies of the forward and reverse reactions
• D. The rates of reaction for the forward and reverse reactions
• E. The concentrations of the reactants and products.

Answer 1

The correct option is D The rates of reaction for the forward and reverse reactions

The rates of reaction for the forward and reverse reactions are equal in a reversible chemical reaction at equilibrium. When the concentrations of reactants and products have become constant, a reaction is said to have reached a point of equilibrium. The consistency of measurable properties such as concentration, color, pressure and density can show a state of equilibrium. The rates of the two opposing reactions have become equal. The amount of products and reactants produced are consistent, and there is no net change.
