Mechanism of the reaction

(1) Reaction making use of first order consecutive reactions

(i) In this kind of reactions, the reactions from the stable intermediate compound before they are finally converted into products.

(ii) For instance, reactants (R) are first converted to intermediate (I) which is then converted to product (P) as

 Thus, the reaction takes place in two steps, both of which are of the first order that is

Step I :  

This means that I is obtained by step I and consumed by step II. In the above given reactions, each stage will have its own rate and rate constant reactant concentration will always decrease and product concentration will always increase as which is shown in figure

(2) Reaction involving slow step : When a  reaction occurs by a sequence of steps and one of the step is quite slow, then rate determining step is slow step. For instance in the reaction

; , if k₁<<k₂ then I is converted into the products as soon as it is formed, we get the conclusion as follows

(3) Parallel reactions : In these type of reactions the reactants are more reactive, which can have different orders of the reactions taking place simultaneously. For example, in a system containing NO₂ and SO_2, NO₂ is consumed in the following two reactions,

         The rate at which the NO₂ disappears will be sum of the rates of the two reactions i.e.,
