In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.
<h3>What occurs if a reaction reaches dynamic equilibrium in a closed system?</h3>
A closed chemical system is said to attain dynamic equilibrium if the rate of the forward reaction is said to have equals the rate of the backward reaction and also the level of concentrations of products and reactants are said to be the same.
Hence, In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.
