In chemistry, the equilibrium of a reaction is the point at which the products and reactants have the lowest free energy. The dynamic equilibrium, on the other hand, is the point at which products are being generated as fast as they are falling apart. This may not be the same as the chemical equilibrium, as enzymes force many reactions far past ...A reaction is at equilibrium if reactants and products are both present, the forward and reverse rates are equal and the concentrations don't change over time. If this is the only reaction in a closed, isolated system, the entropy in the system is constant.
