CHEMICAL EQUILIBRIUM Chemical Equilibrium is the most important and high weightage chapter in chemistry according to NEET Every year 4-5 questions are being asked from this CHAPTER. DIFFICULTY LEVEL of MCQs asked from this chapter is "AVERAGE" CONTENTS : 1. Equilibrium in physical process 2. Equilibrium in chemical process dynamic equilibrium 3. Law of chemical equilibrium and chemical constant*** 4. Homogenous and heterogeneous equilibrium 5. Applications of equilibrium constant 6. Factors affecting equilibrium Characteristics of Equilibrium State 1. It is achieved in a closed system only. 2. It is dynamic, can be attained from either side i.e. from the side of reactants or products. LE CHATELIER'S PRINCIPLE If a system, at equilibrium, is subjected to a change of concentration, pressure or temperature, the equilibrium shifts in the direction that tends to undo the effect of the change. This leads to the following important results: 1. An increas...
