A system is at equilibrium. Which statement is correct?(1 point) Responses The concentrations of the reactants equal the concentrations of the products. The concentrations of the reactants equal the concentrations of the products. There are no changes to the system. There are no changes to the system. The rate of the forward reaction equals the rate of the reverse reaction. The rate of the forward reaction equals the rate of the reverse reaction. The system has been disturbed.

Answer 1

The correct statement regarding a system at equilibrium is: The rate of the forward reaction equals the rate of the reverse reaction.

At equilibrium, the concentrations of the reactants and products do not necessarily have to be equal, and there are still changes happening at the molecular level, but the overall concentrations remain constant because the rates of the forward and reverse reactions are equal.
