Jan 19, 2024 · Equilibrium Class 11 Notes Chemistry Chapter 7. • Chemical Equilibrium. In a chemical reaction chemical equilibrium is defined as the state at which there is no further change in concentration of reactants and products. For example, At equilibrium the rate of forward reaction is equal to the rate of backward reaction.

Apr 24, 2024 · CBSE Class 11 Chemistry Notes Chapter 7: The term “chemical equilibrium” describes the point at which neither the reactants nor the products may alter anymore. The advancing and backward reaction rates stay the same in this scenario. It becomes crucial for students to understand equilibrium to understand more complex subjects.
