NCERT Books for Class 12 Chemistry Chapter 4 - Chemical Kinetics

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.
