Physical Chemistry:

It is that branch of chemistry which applies Mathematics and physics in dealing the concepts of chemistry. We learn chemical systems in terms of physical concepts. We learn about intermolecular forces on the physical properties of materials. Four main areas of physical chemistry are chemical thermodynamics, quantum chemistry, and electro chemistry. Quantum chemistry, surface chemistry, statistical mechanics and kinetics.

Chemical thermodynamics deals with the relation between heat and other forms of energy. We learn about the internal energy of the system which is the sum of the potential and kinetic energy of the particles present in the system. we learn about three laws of thermodynamics.

Chemical kinetics:

How the speed of the reaction can be influenced under different experimental conditions. What are the factors which decide the nature of the reactions. It depends on nature of the reactants. If a reaction involves lesser bond arrangement it occurs at a faster rate than the reaction which involves more bond rearrangement. Physical state (solid.,liquid, Gas) of the reactant also influences the rate of a reaction.

Increase in pressure will increase the collision between the molecules. The reaction occurs at a faster rate.

Catalyst and temperature play important role in the rate of reaction.

Electro chemistry

We learn about inter relation between electrical current and chemical change. In electro chemistry we learn how the ions move toward electrodes and discharged in the respective electrodes.The various application of electro chemistry in day to day life will also be explained.


A chemical reaction which absorbs energy in the form of light is the basis of electro chemistry. We learn the interaction of light with matter and its mechanism.

In physical chemistry. we learn kinetic theory of gases, Boyles'Law,charles'Law, gas equation, vanderwalls equation.Solublity of solute at different temperature in a given solvent. In Physical chemistry we learn about surface chemistry also.When a solid is ex[posed to liquid or a gas reaction occurs at the surface of the solid and its property changes. When aluminum is exposed to air black layer of aluminum oxide forms on its surface which prevents its corrosion. is a pioneer in online tutoring and homework help.
