Chemistry Revision Notes for Class 12 Chapter 4 Chemical Kinetics

Chemical Kinetics also called reaction kinetics deals with the study of rates of chemical reactions. Some of the factors affecting the rate of reaction are:

  • Nature of reactants
  • Light
  • Temperature
  • Reactant physical state
  • Catalysts
  • Concentration
  • Pressure

When the rate of reaction is represented in terms of concentration, it is called the rate law. It is also termed as rate expression or rate equation. t1/2 represents the half-life of a reaction. It is defined as the time for which the concentration of a reactant is reduced to one half of its initial concentration.

Frequently asked Questions on CBSE Class 12 Chemistry Notes Chapter 4: Chemical Kinetics

What is a ‘Reactant’?

Any substance that enters into and is altered in the course of a chemical reaction is called as a ‘Reactant’.

What are ‘Catalysts’?

A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction.

What is ‘Pressure’?

The perpendicular force per unit area, or the stress at a point within a confined fluid is known as ‘Pressure’.
