From Wikipedia, the free encyclopedia
Physical chemistry, is the application of physics to macroscopic, microscopic, atomic, subatomic, and particulate phenomena in chemical systems within the field of chemistry traditionally using the principles, practices and concepts of thermodynamics, quantum chemistry, statistical mechanics and kinetics. It is mostly defined as a large field of chemistry, in which several sub-concepts are applied; the inclusion of quantum mechanics is used to illustrate the application of physical chemistry to atomic and particulate chemical interaction or experimentation.
Physical chemistry is mostly referred to as a macromolecular doctrine, as the majority of the principles on which physical chemistry was founded are composed entirely of macromolecular concepts, such as colloids.
The relationships that physical chemistry tries to resolve include the effects of:
- Intermolecular forces on the physical properties of materials (plasticity, tensile strength, surface tension in liquids).
- Reaction kinetics on the rate of a reaction.
- The identity of ions on the electrical conductivity of materials.
