In a chemical change, a chemical reaction is a state within which each of the reactants and merchandise square measure gift in concentrations that haven’t any more tendency amendment to vary to alter with time in order that there’s no evident change within the properties of the system. This state results once the forward reaction takes at a constant rate because of the reverse reaction. The reaction rates of the forward and backward reactions square measure usually not zero, however they’re equal. Thus, there are not any web changes within the concentrations of the reactants and merchandise. Such a state is understood as dynamic equilibrium.
VARIOUS TYPES OF PHYSICAL EQUILIBRIUM
Types of Physical Equilibrium
Phase Equilibrium:
At 0°C, the quantity of water molecules changing into ice is adequate for the water molecules as the ice melts to create liquid water. the speed of freezing of water is adequate for the speed of melting of ice. Thus, there’s an associate degree equilibrium between solid ice and liquid water.
Ice (s) ⇌ Water (l)
The number of molecules of a liquid changing into vapour is going to be adequate for the number of molecules compressed into liquid in an exceedingly closed instrumentality. the speed of evaporation of liquid water is adequate to the speed of condensation of vapour. The liquid section is in equilibrium with its own vapor section.
Water (l) ⇌ Water (g)
Solute-Solid Equilibrium:
When a matter {in a|during a|in associate degree exceedingly|in a very} saturated resolution is involved with an unmelted matter, the quantity of molecules going (depositing) out of the answer is adequate for the number of molecules coming into (dissolving) from the solid into the liquid. therefore the matter in an exceedingly resolution is in equilibrium with the unmelted solid.
Solute (aq) ⇌ matter (s)
Gas-Liquid Equilibrium:
Gases that don’t react with liquid could dissolve directly associated with the pressure within the liquid. in an exceedingly closed instrumentality, there’s an associate degree equilibrium between the gas within the liquid and also the gas gift higher than the liquid. In soft drinks, as an example, greenhouse emission gas within the liquid is in equilibrium with the gas within the empty house of the instrumentality.
Gas (solution) ⇌ Gas (g)

FAQs:
Q. What square measure the characteristics of physical equilibrium?
Ans. General characteristics of physical equilibrium
The measurable properties become constant.
They are often established solely in a closed vessel.
At equilibrium, the opposing forces become equal.
The equilibrium is dynamic in nature.
At equilibrium, the concentration becomes constant.
What are physical equilibrium and chemical equilibrium?
A physical equilibrium is AN equilibrium state during which the physical state of the system doesn't modify. the reaction is the equilibrium state during which the concentrations of reactants and product isn't modified with time.
What is a physical equilibrium example?
The modification of a substance from one part to a different part is termed a physical method. The equilibrium earned in physical processes is termed physical equilibrium. Example: Ice(s) ⇌ Water(l) . it's a physical equilibrium as a result of no chemical process is concerned.
