CBSE Class 11 Chemistry Chapter 7 - Equilibrium Class 11 Notes

Equilibrium Class 11 Revision Notes

Equilibrium Class 11 Notes – The chapter teaches that the number of molecules that leaves the liquid is equal to the number of molecules returning to the liquid from vapour. Moreover, equilibrium is dynamic in nature. Also, it can be established for both chemical and physical processes. Furthermore, the equilibrium constant has a constant value at a fixed temperature. In addition, at this temperature all the microscopic properties such as pressure, concentration, etc become constant. Besides, Le Chatelier’s principle states that the change in any factor such as pressure, concentration, temperature, etc. will cause the equilibrium to shift to counteract the effect.

Most noteworthy, electrolytes are the substances that conduct electricity in aqueous solutions. Also, acids, bases and salts are electrolytes and they conduct electricity in their aqueous solutions. Moreover, they do so because of the presence of cations and anions. Besides, we can completely dissociate strong electrolytes. Furthermore, the chapter also discusses the role of common ion and the solubility of sparingly soluble salts.
