Physical Chemistry

Physical chemistry involves the concepts of particles encompassing the macroscopic, particulate and subatomic phenomena. It gathers and refines principles from diverse concepts covering motion, dynamics force and time. Physical chemistry provides a method to calculate the rate of reaction. Observing the pattern of membranes in electrochemistry is possible with Physical Chemistry.

Principles of entropy and chemical kinetics determine how fast a chemical reaction is and the stability of the resulting compounds and precipitants. Temperature, pressure and concentration of the particles also play a vital role in chemical reactions. These are the basic variables in the study of reactions. However, other parameters like intermolecular forces play a major role in the speed of the reactions. These parameters are addressed by the laws of physical chemistry.

Avogadro number:

Avogadro number is related to molar mass and it is represented by L, and is dimensionless as with other forms of ratios. The number is of significance in many applications and calculations within the scope of physical chemistry. The earliest approach was to determine the Faraday constant. Faraday Constant is expressed as the charge carried by a single mole of electrons, which is divided by the elementary charge. And it is basically defined as the number of molecules in one gram-molecule of hydrogen.
