The book is compiled in relation to the current programs in physical chemistry for non-chemical higher technical educational institutions. It sets out the main sections of physical chemistry: the structure of matter, chemical thermodynamics, the doctrine of solutions, electrochemistry, the kinetics of chemical reactions, the doctrine of the colloidal state, etc. The book discusses the method of labeled atoms and the chemical effect of radiation, the physicochemical properties of polymers and plastics. The material of the book is illustrated by reference data, graphs and examples. The close relationship of physical chemistry with applied sciences and its application in technology are shown.
