The order of a chemical reaction is defined as the sum of the powers of the concentration of the reactants in the rate equation of that particular chemical reaction. Consider a general reaction: [aA+bB. This method of pseudo first order reaction is useful in the study of chemical kinetics. If one of the reactants is expensive,
