Mass action rate laws:

Mass action kinetics state that the rate of a reaction is the product of a rate constant (k) times (*) the mass(S). The mass in our case is concentration of the substrate (S) of the reaction. kS

Mass action kinetics can be used to model (approximate) the behavior of reversible and irreversible enzymatic reactions for unregulated enzymes that are not near saturation.
