mass-action principle

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

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

   Lei da ação das massas

   • The mass-action principle is fundamental to understanding reaction kinetics.
   • Using the mass-action principle, chemists can predict how changing concentration affects reaction speed.
   • The law of mass action explains why increasing the concentration of a reactant speeds up the reaction.
