The textbook was developed by the staff of the Department of Physical and Colloid Chemistry of the Kazan National Research Technological University, taking into account many years of experience in teaching the discipline . The authors paid special attention to all mathematically complex equations and conclusions and tried to explain in detail the ambiguous and challenging aspects of physical chemistry in students. The textbook fully covers the material provided by the exemplary program of the discipline "Physical Chemistry" and includes four sections: "Fundamentals of Chemical Thermodynamics", "Phase Equilibrium"; "Electrochemistry", "Chemical Kinetics" .. Designed for students of higher educational institutions studying in chemical-technological directions and specialties, as well as for graduate students, researchers, teachers studying physical chemistry
