noun
: a number that expresses the relationship between the amounts of products and reactants present at equilibrium in a reversible chemical reaction occurring at a given temperature, that is relatively independent of the quantities of the species involved, and that represents the ratio of the mathematical product of the concentrations of the reaction products to the mathematical product of the concentrations of the starting materials
