NCERT Solutions for Class 11 Chemistry Chapter 7 Equilibrium

In this chapter, we will discuss the concept of equilibrium in chemical and physical processes and details about equilibrium's dynamic nature. There are some insights about the equilibrium constant, the law of mass action and what are the factors affecting the equilibrium state. It is a lengthy and also an important chapter of class 11 chemistry. In this chapter, there are 73 questions in the exercise. The NCERT Solutions for Class 11 Chemistry Chapter 7 Equilibrium are prepared and solved by chemistry experts. These NCERT solutions help students in the preparation of their class 11 final examination as well as in the various competitive exams like JEE Mains, NEET, BITSAT, etc. 

After studying NCERT Class 11 Chemistry Chapter 7 Equilibrium students will be able to identify equilibrium's dynamic nature involved in chemical and physical processes; explain the law of equilibrium; explain characteristics of equilibria involved in chemical and physical processes; write expressions for equilibrium constants; explain factors affecting the equilibrium state of a reaction; classify substances as bases or acids according to Bronsted-Lowry, Arrhenius and Lewis concepts; also able to classify bases and acids as weak or strong in terms of their ionization constants and calculate solubility product constant.

What is the Equilibrium?

Equilibrium is the state of a process in which the properties like the concentration of the system, pressure, and temperature do not change with the passage of time. It can be established for both chemical and physical processes. At the stage of equilibrium, the rate of forwarding and reverse reactions are equal. The state of equilibrium can only be achieved if the reversible reaction is taking place in a closed system.
