Course detail
FSI-WCTAcad. year: 2023/2024
Course deals with basic terms, principles and relations of classical chemical thermodynamics and kinetics, which are necessary for understanding of physical-chemical problems of material science. Chemical thermodynamics is focused on basic thermodynamic principles, variables and relations, description of equilibrium in single- and multi-component homogenous and heterogeneous systems, and on phase diagrams. Multi-component chemical reactive systems and problem of capillarity are also mentioned.Kinetics shows basic kinetic philosophy of physical-chemical processes in heterogeneous systems, particularly phase transformations diffusion and sintering.
