NCERT Books for Class 12 Chemistry Chapter 4

A Brief Into The Chapter

The concept of chemical kinetics helps us in understanding how chemical reactions occur. Chemical kinetics is a very important chapter as all the other chapters are connected to this concept therefore it is advisable to study this chapter in-depth so that nothing is missed out. To make things even Vedantu’s team has curated study material for the students to access easily. We have provided revision notes for class 12 electrochemistry students that will help them to study the chapter in-depth. 

This chapter covers various important topics that are important to study in order to score exceedingly well in class 12 board exam examples: difference between elementary and complex reactions, the difference between molecularity and order of reaction; it defines rate constant briefly, and describes collision theory.

Subtopics Of The Chapters

The subtopics included in the NCERT book of class 12 in ch 4 are:

  • 4.1 Rate  of a Chemical  Reaction

  • 4.2 Factors Influencing Rate of a Reaction

  • 4.3 Integrated  Rate Equation

  • 4.4 Pseudo First Order Reaction

  • 4.5 Temperature Dependence of the Rate of a Reaction

  • 4.6 Collision Theory of Chemical Reactions

Chemical Kinetics

Chemical kinetics can be studied as chemical reactions with respect to reaction rates, the effect of various variables, rearrangement of atoms, and formation of intermediates. It is a branch of chemistry that deals with the rates of chemical reactions. As a part of thermodynamics. It is also known as reaction kinetics. There are various factors affecting reaction rate such as Nature of the reactants, physical state, the surface area of solid-state, concentration, temperature, catalyst, pressure, absorption of light. Mathematical representation of the rate of a reaction is given by rate law. The NCERT book of class 12 provides a comprehensive understanding of chemical kinetics. The book has a whole chapter dedicated to the study of chemical kinetics called ch -4 chemical kinetics.

The Collision Theory Of Chemical Reactions

Collision theory is used to predict the rates of chemical reactions, particularly gasses. This theory has proven to be extremely useful and has made great progress over time. It is part of our day-to-day fast-paced life, be it fast-moving vehicles or manufacturing plants. This theory is based on the assumption that in order for a chemical reaction to occur, the reaction particles must collide with one another. The kinetic theory of gasses states that for every 1000 binary collisions, there will be only one event in which three molecules simultaneously come together.  Students can study this theory in depth in the class 12 NCERT book in the ch -4 called Chemical kinetics.

FAQs on NCERT Books for Class 12 Chemistry Chapter 4 - Chemical Kinetics

1. Why do we need to study Chemical kinetics?

Chemical kinetics is a part of the CBSE curriculum and holds a great weightage in the class 12 syllabus. If a student wants to score a good percentage then it is advisable to study the chapter in-depth. It involves complex numerical problems which can only be solved after gaining knowledge of the technical equations, that is how they work and how they came into existence. This chapter will help you gain knowledge about various important topics such as the collision theory of chemical reactions and will help you to derive integrated rate equations for the zero and first-order reactions.

2. Where can I find class 12 study material on the ch chemical kinetics?

With everything getting digitized, the study material for various chapters is available on the internet and is easily accessible.  The Vedantu team has curated a well-read and detailed study material for revisions and other notes that come in handy when a student wants to learn in-depth or needs to revise an hour before the exam. The link to access class 12 revision notes is provided at the beginning of this page. It is easily accessible as you can download it for free.

3.  What are the important topics in Chapter 4 chemical kinetics?

Chemical kinetics is a very interesting chapter that can help you fetch good marks in the CBSE board examination. The important topics covered in this chapter are-  Rate of a Chemical  Reaction, Integrated  Rate Equation, Collision Theory of Chemical Reactions, Temperature Dependence of the Rate of a Reaction, it will help you to easily distinguish between elementary and complex reactions.

4. Is reading NCERT books enough to score well in the Class 12 CBSE board examination?

More than half of the question paper contains questions that have already been studied in the NCERT textbooks. With everything getting digitized, sites like Vedantu can help a student gain more knowledge to excel in the board examination.  Vedantu has simplified the important topics that some students may find difficult to grasp. With its revision notes and solutions provided to the questions at the end of the chapter, one can easily score well in the Class 12 CBSE  board examination.

5.  Are the exercises difficult to solve in ch 4 chemical kinetics?

The exercises given at the end of the chapter assess the analytical and critical thinking skills of a student. They determine how much knowledge the student acquired while studying the chapter. For exercise solutions, Vedantu’s exercise solutions are easily available on the web. You can find them on
