Question

Which describes a solution that contains a system at equilibrium? One in which the color of the solution is changing slowly, or one in which the color is not changing. Explain your answer.

Answer 1

Answer:

A solution that contains a system at equilibrium is the one in which there is no change in color

Explanation:

If the color of the solution changes slowly it means that the equilibrium shifts towards the right. This happens when we add the reactant and the equilibria move towards the right that is away form the reactant increasing the product formation. But when there is no change in color it means the reaction is constant and there is a state where the concentrations of reactant and product are not changing and are constant.

Hence, the solution in which the color is not changing is at equilibrium.
