    it is. equilibrium is reached when the concentrations (or amounts) of reactants and products remains constant over time

    It was B. The correct answer is: balls are being thrown in both directions, but there is no net change in the number of balls on each side of the fence. At equilibrium, balls are being exchanged over the fence at equal rates, such that the net number of balls on either side does not change. Remember that there are not necessarily equal numbers of balls on each side of the fence at equilibrium.

    the amounts dont have to be \(equal\), they just can't \(change\) over time
