Consider the reaction. When does the given chemical system reach dynamic equilibrium? when the forward and reverse reactions stop when the rate of the forward reaction is higher than the rate of the reverse reaction when the concentration of the reactants is higher than the concentration of the products when the rates of the forward and reverse reactions are equal

when the rates of the forward and reverse reactions are equal

Explanation:

The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction.

A chemical equilibrium is dynamic in nature as forward and backward reactions continue for indefinite time and never stops.

the answer to this question is 3.
