The determination of reaction order
How to determine order of reaction?
Or how to determine reaction order?
- Using the differential rate expression method
- Using the integral rate expression method
- Using Half Life time method
- Using the isolation method
1.The differential rate expression
r = kncn …….(1)
ln r = ln kn + n ln c ………..(2)

2.Using the integral rate expression
3.Half Life Time method
How to determine the order of reaction from the Half Life Time method?
Use this type of equation For the determination of order of the reaction. Where different types of half life time For different types of molar concentration of reactant. We can easily calculate n value using the experimental data. What is the order of reaction we can easily calculate? Yes, easily calculate the order of reaction using the half life time method.
