Physical Chemistry I

The lecture is the first part of the Physical Chemistry course, which is directed predominantly for students in chemical fields. It brings the base of thermodynamics directed for its use in sciences. In parallel with the lecture there are held Calculations in Physical Chemistry, where the understanding of the theoretical matter is trained.
