Physical Chemistry is a textbook for courses in physical chemistry taught to chemistry students at both the undergraduate and graduate level. It develops the fundamentals of physical chemistry in a logical sequence from the simple to the more complex, from atomic and molecular structure to properties of condensed matter, then to statistical and thermodynamic properties of systems in equilibrium and then to transport phenomena and chemical reaction processes. The conceptual structure of physical chemistry is emphasized throughout the presentation. the text assumes no prior knowledge of physical chemistry, but carries the reader to a level appropriate for graduate study.
