Relation Between the Equilibrium Concentrations
When a chemical system is in perfect equilibrium, it means that the reactants are continuously reacting to form products, and the products are simultaneously decomposing to form the reactants. The reversible arrow is used to depict such a scenario. The equilibrium constant, K, can be written for this system. However, any change in the concentrations of the species results in a shift from the equilibrium position. The reaction quotient, Q, is affected and, based on Le Chatelier's Principle, the direction of shift is such as to restore the value of Q to K.
