Question

What is Reactions which Possess Fractional Order of Reaction?

Answer

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.
