Chapter 4 - Chemical Kinetics

The board exams are one of the most critical tests that a student in class 12 has to go through. The marks that the student obtains in his or her board examination determine the college or university where hey can take admission. This examination is often considered as the defining point in a students life, which could lead them to have a good future.

From class 6, you start learning the basics of Chemistry. The subject Chemistry for Class 12 could be complicated as there are various difficult contents within the subject. NCERT Solutions for Class 12 Chemistry Chapter 4 can assist you to progress through your board examinations with flying colours. At UrbanPro you can find answers to chemical kinetics for class 12 NCERT Solutions.

Let’s have a look at the contents of Chapter 4- Chemical Kinetics

4.1. Introduction

4.2. Factors Affecting The Rate Of Chemical Reaction

4.3. Rate of Chemical Reaction

4.4. Rate Constant and Order of Reaction

4.5. Molecularity

4.6. Integrated Rate Law

4.7. Zero Order Reaction

4.8. Rate Equation For First Order Reaction

4.9. Pseudo First Order Reaction

4.10. Determination Of Order Of Reaction

4.11. Temperature Effect on Constant Rate

4.12. Theory of Collision

In Chapter 4 of Chemistry for Class 12, you will learn – 

4.2. In this section, you will learn about the factors which affect the rate of chemical reaction, which are: 1. State of substance and area of surface, 2. The solvent’s consistency, 3. The pressure of the system (for gaseous reactions), 4. Temperature, and 5. Effect of catalyst.

4.3. In this portion, you will study the progress of chemical reactions and the function it plays in measuring the concentration of reactants and how gaseous reactions measures pressure instead of concentration, that is, within a definite time interval. You will also learn how with an increase in time during the progress of the reaction, the concentration of the reactants will decrease, and the concentration of products will increase.

4.4. This portion of the chapter will teach you about the order of reaction and the rate constant. Here you will learn how the simple rate equation can be obtained by taking the pure reactant from most reactions where the rate is proportional to the exponent of the concentration of the reactant.

4.5. Here you will learn about Molecularity which is the second most important term in reaction. The term “Molecularity” can be defined as an elementary reaction but not for a complex reaction. You will study the definition of Molecularity and the reactions.

4.6. After you have seen that the change in concentration on the rate is the differential rate equation, but it doesn’t always determine the instantaneous rate. You will then learn about the integrated rate law, which helps to simplify the determination of concentration at different time intervals.

4.7. The integrated rate law that you’ve studied in the previous chapter can be applied while you try to figure out the zero-order reaction. You will study the definition of zero-order reaction, where it is found and how integrated rate law could be applied, here.

4.8. The integrated rate law is also applied in the rate equation for the first-order reaction. Here there will be a thorough explanation give about the first-order reaction with multiple examples.

4.9. For this section, you study the pseudo-first-order reaction, which is explained with the help of examples.

4.10. Here you will learn about the four methods used for determination of the order of the reaction.

4.11. In this portion, you will study how the rate of concentration increases with an increase in temperature and how the results are derived from the Arrhenius equation.

4.12. In this section, you will study about the Theory of Collision, which was developed by William Lewis and Max Trauz and how it deals with the mechanistic and energetic matter of reaction.

In this chapter for Chemical Kinetics, NCERT Solution has been explained with the help of examples along with their solutions for understanding the contents of this chapter. You should also refer to Chemical Kinetics NCERT solutions pdf download.
