Reactions which Possess Fractional Order of Reaction…

Reactions which Possess Fractional Order of Reaction in chemical kinetics, a fractional order of reaction indicates that the reaction rate depends on the concentration of one or more reactants to a fractional power (less than 1). Here are a few examples of reactions that possess fractional order of reaction:
(i) In many electrochemical reactions, the rate of the reaction is proportional to the concentration of the reactants raised to a fractional power.
(ii) Adsorption reactions often exhibit fractional order kinetics because the rate of adsorption is proportional to the concentration of the adsorbate raised to a fractional power.
(iii) Many enzymatic reactions exhibit fractional order kinetics because the rate of the reaction is proportional to the concentration of the substrate raised to a fractional power.
