RECAPITULATION Repeating the basic concepts and functions in chemical thermodynamics and their properties. STATE BEHAVIOR State equations (virile state equation, Redlich-Kwongova, Benedict-Webb-Rubin). Application to the mixtures. Behavior of liquids status and its estimation. THERMODYNAMIC QUANTITIES Calculation of thermodynamic quantities of pure components and mixtures in systems containing substances in faseous and liquid state. APPLICATIONS OF THERMODYNAMIC QUANTITIES Calculation of heat, adiabatic processes, balance of enthalpy, reaction enthalpy. EXTENSIVE CRITERIA OF EQUILIBRIUM Use of thermodynamic functions in determining the steady state under different boundary conditions. The importance of Gibbs energy in practice. CALCULATION OF CHEMICAL EQUILIBRIUM Calculation of chemical equilibrium in the system with one or more chemical reactions. Minimization of Gibbs energy. PHASE EQUILIBRIUM Calculation of phase equilibria in real systems (systems with azeotropic point, the use of activity coefficient, disintegration of the system into two liquid phases, the solubility of gases at low and high pressure, the solubility of solids, phase diagrams with congruent melting compound). CHEMICAL KINETICS Simultaneous course of many chemical reactions in the system and the dependence of the concentration of substances on time (reversible, competitive and simultaneous reactions).
