Dynamic equilibrium refers to a state in which a system experiences continuous change but remains balanced overall. In this state, the rates of opposing processes are equal, leading to no net change in the system. For example, in a chemical reaction, the rate of the forward reaction matches the rate of the reverse reaction, resulting in stable concentrations of reactants and products. This concept is often illustrated using the example of a chemical reaction in a closed container. When a reaction reaches dynamic equilibrium, the concentrations of the substances involved remain constant, even though the individual molecules are still reacting. This balance is crucial in various fields, including chemistry and biology.
