law of mass ac·tion

the rate of a chemical reaction is proportional to the concentrations of the reacting substances; when the forward reaction rate equals the reverse reaction rate (that is, at equilibrium) then, at constant temperature, the product of the concentrations of all the products divided by the product of the concentrations of all the reactants is itself a constant (Keq).

law of mass action

The principle that the rate of a chemical reaction is proportional to the molar concentration of the reacting substances.

law of mass action

a law stating that the rate of progression of a chemical reaction is proportional to the concentration of the reactants.

The Mass Law is also observed where the thinner a construction gets, the overall sound transmission loss decreases, and more sound is transmitted through the glazing.
This has been accomplished by increasing the density of the elastomeric alloy to take advantage of the mass law effect.
