1.	What is chemical equilibrium? What are its characteristics?
Answer» Chemical equilibrium is a state of a reversible chemical reaction where the, Rate of forward reaction = Rate of backward reaction. No change in the amount of the reactants and products takes place. Characteristics of equilibrium: 1. In a chemical equilibrium, the rates of the forward and backward reactions are equal. 2. The observable properties such as pressure, concentration, colour, density, viscosity etc., of the system remain unchanged with time. 3. The chemical equilibrium is a dynamic equilibrium, because both the forward and backward reactions continue to occur even though it appears static externally. 4. In physical equilibrium, the volume of all the phases remain constant.

Answer»

Chemical equilibrium is a state of a reversible chemical reaction where the,

Rate of forward reaction = Rate of backward reaction.

No change in the amount of the reactants and products takes place.

Characteristics of equilibrium:

1. In a chemical equilibrium, the rates of the forward and backward reactions are equal.

2. The observable properties such as pressure, concentration, colour, density, viscosity etc., of the system remain unchanged with time.

3. The chemical equilibrium is a dynamic equilibrium, because both the forward and backward reactions continue to occur even though it appears static externally.

4. In physical equilibrium, the volume of all the phases remain constant.
