Course Physical Chemistry A+B provides a comprehensive overview of physical chemistry as a discipline used to understand the principles and calculations in chemistry and chemical engineering. The course begins with chemical thermodynamics and is based on a molecular point of view rather than on a classical continuous approach; therefore, the necessary basics of statistical thermodynamics are discussed in parallel. Part A (fall term) ends with phase equilibria. Part B (spring term) is devoted to chemical equilibrium, chemical kinetics, electrochemistry, and physical chemistry of surfaces. Other traditional fields of physical chemistry – quantum theory and spectroscopy – are not covered by the course.

Students will:

1. Understand fundamentals of chemical thermodynamics including basics of statistical thermodynamics,

2. Be able to apply methods of physical chemistry in a variety of fields of chemistry and chemical engineering;

3. Be able to formulate the problem, look for the necessary data in the literature, and communicate with experts more difficult tasks.
