(4) a chemical condition in which the rates of forward and reverse reactions are equal and the concentrations of reactants and products do not change with time. One of two major chemical conditions affecting drainage chemistry.
The state of a chemical reaction in which the concentration of all products and reactants is constant and the rates of the forward and reverse reactions are equal.
a state of balance in which forward and reverse chemical reactions are taking place at the same rate; no net change in the amounts of reactants and products occurs in the chemical system. (see equilibrium, dynamic equilibrium)
