law of mass action

• Princípio fundamental da química segundo o qual a velocidade de uma reação química é proporcional ao produto das concentrações dos reagentes, cada uma elevada a um expoente igual ao seu coeficiente estequiométrico na equação química balanceada.

A fundamental principle in chemistry stating that the rate of a chemical reaction is proportional to the product of the concentrations of the reactants, each raised to a power equal to its stoichiometric coefficient in the balanced chemical equation.

   Lei da ação das massas

   • The law of mass action explains why increasing the concentration of a reactant speeds up the reaction.
   • Using the law of mass action, chemists can calculate the equilibrium constant for a reaction.
   • The law of mass action is fundamental to understanding how chemical systems reach equilibrium.
