The English edition of this book has been translated from the manuscript of the 2nd Czech edition. It has been changed slightly in some places and enlarged on in others on the basis of further experience gained in teaching physical chemistry at the Institute of Chemical Technology in Prague.
The book begins with illustrations and problems on the atomic structure and the fundamentals of quantum mechanics. Subsequent chapters cover the kinetic theory of ideal gas; fundamentals of thermodynamics; states of matter; phase equilibrium; chemical equilibrium and third law of thermodynamics; electrochemistry; reaction kinetics; surface phenomena and colloidal systems; and molecular structure and physical properties.
Collection of Problems in Physical Chemistry provides illustrations and problems covering the field of physical chemistry. The material has been arranged into illustrations that are solved and supplemented by problems, thus enabling readers to determine the extent to which they have mastered each subject. Most of the illustrations and problems were taken from original papers, to which reference is made. The English edition of this book has been translated from the manuscript of the 2nd Czech edition.
