What are two conditions for equilibrium?

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. 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.

Complete answer:
As we know that in equilibrium, the two conditions are important for attaining the position in the reaction.
The two condition for equilibrium is given below,
1.The resultant force or sum of all external force on the object in the chemical reaction must be equal to zero.
2.The resultant torque or sum of all external torque acting on the object in the chemical reaction must be equal to zero.
According to the above discussion, we conclude two conditions for equilibrium are force and torque of the object in the chemical reaction.

Note:
As we know that in chemical reactions, 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.
