The textbook briefly outlines the basic principles of chemical thermodynamics and their application to the calculation of thermodynamic chemical reactions. The textbook is intended for students of higher educational institutions studying in the master's program "Materials Science of Nanomaterials and Electronic Components" in the direction of master's training "Technical Physics". It can also be used when teaching students in the areas of training "Materials Science and Technology of Materials", "Metallurgy", in advanced training systems, in institutions of additional professional education.
