Dynamic equilibrium
exists once a reversible reaction ceases to change its ratio of reactants/products, but substances move between the chemicals at an equal rate, meaning there is no net change. It is a particular example of a system in a steady state
A reversible process is said to be in dynamic equilibrium when the forward and reverse processes occur at the same rate, resulting in no observable change in the system.Once dynamic equilibrium is established, the concentrations or partial pressures of all species involved in the process remain constant.
