Law of Chemical Equilibrium Definition

The Law of Chemical Equilibrium is a relation stating that in a reaction mixture at equilibrium, there is a condition (given by the equilibrium constant, Kc) relating the concentrations of the reactants and products. For the reaction

aA(g) + bB(g) ↔ cC(g) + dD(g),
Kc = [ C ]c·[ D ]d / [ A ]a·[ B ]b
