Final answer:
Dynamic equilibrium is a state in chemistry where forward and reverse reactions occur at equal rates, resulting in no net change in reactant and product concentrations. It represents a balanced state with continuous reactions on the microscopic level while macroscopic properties remain constant.
Step-by-step explanation:
Dynamic equilibrium in chemistry refers to the condition where a reaction occurs continuously, with the forward and reverse processes happening at equal rates, leading to a state where there is no overall change in the concentrations of the reactants and products over time. This is a central concept in understanding chemical reactions and is essential to various scientific and engineering applications.
The composition of an equilibrium mixture does not depend on the direction from which equilibrium is approached, indicating that whether the system reaches equilibrium from the side of the reactants or the products, the final state will be the same. Such an equilibrium is portrayed using equations with a double arrow, suggesting that the reaction is in a state of balance. Importantly, while the macroscopic properties remain constant, the reactions continue microscopically, highlighting the dynamic nature of this state.
