Final answer:
Dynamic equilibrium in chemistry refers to a state where the rate of the forward reaction and the rate of the reverse reaction are equal, resulting in no net change in the concentrations of reactants and products over time.
Step-by-step explanation:
Dynamic equilibrium in chemistry refers to the equilibrium state of a reversible reaction when the rate of the forward process is equal to the rate of the reverse process. This concept is pivotal for understanding how chemical reactions reach a state where the composition remains constant over time, despite continuous motion at the molecular level. An equation representing dynamic equilibrium is typically indicated by a double arrow, signifying that the reaction is occurring simultaneously in both directions, and at the same rate.
When this state is reached, it means there is no net change in the concentration of reactants and products over time, even though the entities are still reacting with each other. This balance of rates ensures that the forward and reverse reactions continue indefinitely without shifting the overall concentrations of the chemical species involved.
