The word 'equilibrium' has broad meaning in different fields such as health, economic, engineering, physics, chemistry etc. Equilibrium is the state of balance or stable situation where opposing forces cancel each other.
The change of substance from one phase to another phase is called physical process. The equilibrium attained in physical processes is called physical equilibrium.
What we are going to study
In this chapter we are going to study about physical and chemical equilibrium, Dynamic nature of chemical equilibrium, Law of mass action (Guldberg and Waage) and Le Chatelier's Principle.
When you have finished studying this unit, you should able to:
- understand physical and chemical equilibrium and dynamic nature of chemical equilibrium.
- state the law of mass action and to derive it.
- show the expression for equilibrium constant and its importance.
- derive the relationship between Kp and Kc. state Le-Chatlier's principle and its applications.
Just scroll down to view the complete handwritten note of chemical equilibrium chapter of class 11 chemistry. If the images are not clear then you'll find the notes PDF at the end of this article.
If you want the complete notes of chemical equilibrium chapter including some important questions then you can view the PDF given below. Class 11 chemical equilibrium chapter contains very important notes which seems impossible to provide in image format. So, we have made a PDF containing all the notes.
Chemical Equilibrium Class 11 Notes PDF
As mentioned before, it's impossible for us to provide the image of class 11 chemical equilibrium chapter notes one by one. But the PDF version has made our work easier. The PDF given below consists of all the required notes of class 11 chemical equilibrium chapter.
If some important topics are missing from this notes then you can inform us. We will add the missing topics in this notes as soon as we hear about them. So, make sure to inform us about any mistakes that you may find.
