NCERT Solutions for Class 11 Chemistry Chapter 7 

NCERT Solutions for Class 11 Chemistry Chapter 7 can be used as reference material by students while preparing for exams. The solutions have answers to all the questions that are asked at the end of the Chapter 7 in the NCERT Chemistry book. 

NCERT Solutions Class 11 Chemistry Chapter 7

The NCERT Solutions for Chapter Equilibrium in Class 11 is a reliable study material available to students. It provides answers to all of the questions in Chapter 7 of Chemistry.  Let’s look at the topics that are covered in Chapter 7 solutions:

Chapter 7 Equilibrium

The chapter on equilibrium in chemical and physical processes gives a brief overview of the various concepts of equilibrium in chemical and physical processes, as well as details on how equilibrium is dynamic. This chapter also covers the law of mass action, various factors affecting equilibrium, and the equilibrium constant based on Le Chatelier’s principle. Because it explains how objects behave, equilibrium is the most important part of chemistry.. Equilibrium is explained as chemical theories and models in the NCERT Chapter 7 CBSE Chemistry Class 11 book. 

7.1 Equilibrium in Physical Processes

This topic teaches students about the equilibrium between different physical properties when the chemical composition remains constant. Solid-Liquid equilibrium, Liquid-Vapour Equilibrium, and Solid-Vapour Equilibrium are all examples of equilibrium. 

7.2 Equilibrium in Chemical Processes

Equilibrium in Chemical Process or Dynamic Equilibrium is a process in which the forward and reverse reactions of a chemical equation occur at the same rate with no net change in the product and reactant ratio. 

7.3 Law of Chemical Equilibrium and Equilibrium Constant

The topic discusses concepts such as the connection between the concentration levels of reactants and products in an equilibrium mixture. The topic addresses questions such as:

• What is the relationship between the concentration of reactants and the products in an equilibrium mixture?
• How can we calculate equilibrium concentrations from initial concentrations?
• What factors can be used to change the composition of an equilibrium mixture?
• How can an equilibrium mixture’s composition be altered?

7.4 Homogeneous Equilibria

Homogeneous Equilibrium refers to a reaction in which the reactants and products are in the same physical state. 

For instance, 2SO2 (g) + O2 (g) = 2SO3 (g) 

Sulphur and oxygen are in the same state as each other, which is gaseous. 

7.5 Heterogeneous Equilibria

Heterogeneous Equilibrium is a reaction in which the reactants and products are in different physical states. 

For instance, 3Fe (s) + 4H2O (g) = Fe3O4 (s) + 4H2O (g) 

Iron and iron oxide are solid in this state. However, the state of water and hydrogen gas is gaseous. 

7.6 Applications of Equilibrium Constants

Students learn how to use the equilibrium constant to calculate equilibrium concentrations, predict the extent of a reaction based on its magnitude, and predict the direction of a reaction. The calculation of equilibrium concentrations is covered in this topic. 

7.7 Relationship between Equilibrium Constant K, Reaction Quotient Q and Gibbs Energy G

The Equation Constant K, the Reaction Quotient Q, and the Gibbs Energy G have a relationship. The study of such quantitative relationships between different types of energy is known as thermodynamics. J.W. Gibbs, who is discussed in this section, represents a mathematical expression of this thermodynamic view of equilibrium. 

7.8 Factors Affecting Equilibria

This topic discusses the various factors that influence equilibria as well as the factors that affect equilibria. 

7.9 Ionic Equilibrium in Solution

For weak electrolytes, the ionic equilibrium is the equilibrium established between the unionised molecules and the ions in a solution. Electrolytes include acids, bases, and salts, which can act as both strong and weak electrolytes. 

7.10 Acids, Bases and Salts

This topic reviews the concepts of acids, bases, and salts, as well as three acid and base-based theories. Arrhenius Acids and Bases, Brönsted-Lowry Acids and Bases, and Lewis Acids and Bases are those three theories. 

7.11 Ionisation of Acids and Bases

When a neutral molecule is exposed to a solution, it undergoes ionisation, which is the process by which it splits into charged ions. Students will study Arrhenius’ theory, which states that acids are compounds that dissociate in an aqueous medium to produce hydrogen ions, or H+ (aq). This section also covers the differences between dissociation and ionisation. 

7.12 Buffer Solutions

In this section, students will learn what a buffer solution is, its types, the mechanism of buffering action, preparation of acid and base buffer solutions, the Henderson-Hasselbalch Equation, Buffering capacity and much more. 

7.13 Solubility Equilibria of Sparingly Soluble Salts 

When studying a salt’s properties and the properties of the solution it forms with a particular solvent, its solubility in that solvent is always an important factor to consider. Students will study solubility product, the differences between solubility product and ionic product, their significance and more. 

Class 11 Chemistry Chapter 7: Distribution of Marks

The question-wise weightage  varies for different questions related to Chapter 7. Each question is graded according to the importance of the topic. The chapter contains a total of 73 questions, which are divided into three categories: short type questions, long type questions, and numerical problems. These questions are based on a variety of equilibrium concepts and laws of equilibrium experiments. 

There are one-mark questions with very short answers. Then there are the two-mark short-answer questions, which may include definitions as well. The three-mark questions may include definitions as well as numerical data. Some of the long-answer questions are worth 5-marks.
