Answer:
A
Explanation:
A reactionis said to be at equilibrium when the rate of forward reaction equals the rate of reverse reaction. That means the rate at which the product is formed equals the rate at which the reactants are reformed. The colour of the solution does not change at this point because the both reactions are exactly balanced.
A solution that contains a system at equilibrium in which the color is not changing due to the rate that the product forms is equal to the rate the reactant reforms.
What is equilibrium?
A system is said at equilibrium state in which the formation of product is equal to the formation of reactant because both are formed at the same rate so we can conclude that color is not changing due to the rate that the product forms is equal to the rate the reactant reforms is the correct answer.
