The study of macroscopic, subatomic, atomic and particulate phenomena related to chemical systems is referred to as physical chemistry. It is primarily concerned with the application of principles, concepts and practices of physics to chemical systems. Some of these are force, time, motion, energy, thermodynamics, quantum chemistry, statistical mechanics, chemical equilibrium and analytical dynamics. Major sub-domains of physical chemistry are quantum chemistry, spectroscopy, chemical thermodynamics and chemical kinetics. It is also involved in the study of surface science, electrochemistry of cell membranes, the effect of reaction kinetics on the rate of a reaction and intermolecular forces that act upon the physical properties of materials. This book provides comprehensive insights into the field of physical chemistry. Some of the diverse topics covered herein address the varied branches that fall under this category. Those in search of information to further their knowledge will be greatly assisted by this book.
