Question

What do you mean by the equilibrium of a body?

Answer 1

Hint: We need to know that the equilibrium is nothing but equal concentration between the forward reaction and reversible reaction. There are two types of equilibrium. These types of equilibrium depend on the nature equilibrium will occur in the object. There is chemical equilibrium and physical equilibrium. The physical equilibrium is nothing but the change of phase of matter with time.

Complete answer:
As we know that the equilibrium is nothing but the value of net force acting on the body is equal to zero. In other way, equilibrium means no change in the state of motion or the state of rest of the body, when we apply forces.
According to the above discussion we conclude that the equilibrium of a body means the value of net force acting on the body is equal to zero.

Additional information:
In this physical equilibrium is further classified as five types. These types of physical equilibrium depend on the state of the substance. There are solid-liquid equilibrium, solid-vapour equilibrium, liquid-vapour equilibrium. This equilibrium is divided into two types. This classification is based on the phase of the equilibrium that is attained in the reaction. There are homogeneous equilibrium and heterogeneous equilibrium.

Note:
 In chemical reaction, equilibrium is divided into the two types. There is equilibrium concentration and equilibrium pressure. The equilibrium concentration and equilibrium pressure are important for the chemical reaction. The equilibrium concentration depends on the concentration of the reactant and product of the chemical reaction. The equilibrium pressure is dependent on the pressure of the reactant and product of the chemical reaction. The equilibrium constant of the reaction depends on the equilibrium of the forward reaction and reversible reaction.
