What is physical chemistry?

physical chemistry The branch of chemistry that is devoted to the study of the behavior of matter at the atomic or molecular level. It also includes the study of the properties of substances at various scales, macroscopic scale from which particles that are visible to the naked eye, on the subatomic scale electron like very small subatomic particles are involved.

microscopic scale-

The microscopic scale deals with the properties of substances that can only be seen by the human eye. optical Can be seen with the help of instruments that magnify matter such as microscopes.

of crystal shape and structure study Belongs to this scale. crystal of large sections of crystals of the structure of behavior which are used in bridges and airplanes.

atomic scale-

  • The properties of matter on the atomic scale differ from element to element.
  • However, some elements exhibit similar properties and are grouped together in the periodic table.
  • Some examples of properties of matter studied in physical chemistry at the atomic scale include atomic mass and atomic number.
  • The value of the atomic radius of elements can be used to determine the bond length between two atoms in a molecule.

Branches of Physical Chemistry-

chemical problems The way in which physics can be applied to explain or solve problems is an important aspect of physical chemistry. concepts makes to. Some of the branches of physical chemistry that study these problems are described below.

  • The interaction between matter and electromagnetic radiation is studied in the branch of physical chemistry known as spectroscopy.
  • Quantum chemistry studies the strength and shape of chemical bonds and the way the nuclei of atoms move.
  • Chemical thermodynamics is the study of the spontaneity of a chemical reaction and the properties of chemical mixtures.
  • Chemical kinetics is related to the feasibility and rate of chemical reactions as well as many other factors that affect the rate of a reaction such as the presence of a catalyst or the concentration of reactants.
