Decomposition of Azomethane
Azomethane (CH3-N=N-CH3), also known as dimethyl diazene, is an organic compound commonly used as a reagent in organic chemistry. At very low concentrations, the decomposition of azomethane follows second order kinetics.
Explanation:
Second Order Reaction
A second order reaction is characterized by a rate equation that is proportional to the square of the concentration of the reactant(s). In the case of azomethane decomposition, the rate equation can be represented as:
Rate = k[Azomethane]^2
where [Azomethane] represents the concentration of azomethane and k is the rate constant.
Reasoning:
The decomposition of azomethane involves the breaking of the N=N bond, resulting in the formation of two methyl radicals. Since the reaction involves the collision of two azomethane molecules, the rate of the reaction is proportional to the product of their concentrations, [Azomethane]^2, making it a second order reaction.
Experimental Evidence:
Experimental studies have confirmed that the decomposition of azomethane follows second order kinetics. By monitoring the change in azomethane concentration over time, the rate constant can be determined and the reaction order can be established.
Importance of Reaction Order:
Determining the reaction order is crucial for understanding the kinetics of a reaction. It allows us to predict how changes in reactant concentrations will affect the reaction rate. In the case of azomethane, knowing that it follows second order kinetics can help in designing appropriate reaction conditions and optimizing reaction parameters.
In conclusion, the decomposition of azomethane at very low concentrations follows second order kinetics. This is evidenced by the rate equation, experimental studies, and the nature of the reaction mechanism.

The rate expression for decomposition of azomethane is:
Where, k1, k2 and k3 are rate constants of the 3 intermediate reactions involved in azomethane formation.
At low concentration, k2 CAzo << k3
Hence, rN2=k1CAzo2.
