Chemical equilibrium occurs in a chemical reaction when the rate of the forward reaction equals the rate of the reverse reaction, resulting in no net change in the concentrations of reactants and products. At equilibrium, the system is dynamic, meaning the reactions continue to occur, but the concentrations of the reactants and products remain constant over time. The equilibrium constant, K c K c ​ , is a numerical value that expresses the ratio of the concentrations of products t...
