Consider the reaction.

when does the given chemical system reach dynamic equilibrium?
1)when the forward and reverse reactions stop
2)when the rate of the forward reaction is higher than the rate of the reverse reaction
3)when the concentration of the reactants is higher than the concentration of the products
4)when the rates of the forward and reverse reactions are equal

The correct answer is 4. The dynamic equilibrium is a chemical equilibrium, in which two reversible reactions occur at the same speed, in both directions, maintaining the concentration of reactants and products constant over time. In other words, in dynamic equilibrium two opposite reactions occur at the same speed in the opposite direction.
