Classification of reactions based on order of the reaction

Classification of reactions based on the order of the reaction

Classification of reactions based on the order of the reaction is as follows

1.     First-order reaction

2.     Second-order reaction

3.     Third-order reaction

First-order reaction

• A reaction of which sum of order with respect to reactants participated in the reaction is one is called as first-order reaction
• Example:-Decomposition of nitrogen pentaoxide is a first-order reaction

Second-order reaction

• A reaction of which sum of order with respect to reactants participated in the reaction is two is called as second-order reaction
• Example:-saponification of ester

Third-order reaction

• A reaction of which sum of order with respect to reactants participated in the reaction is three is called a third-order reaction
• Example:-production of N₂O from NO
