##### Module Details

At the end of the course, the student will be able to:

- combine the 1st and 2nd law of thermodynamics in order to compute the exchange of heat and work in physical processes
- compute practically all thermodynamic properties of a physical system (pure substance or mixture) from some volumetric data (PVT properties)
- compute phase behavior of multi-component systems corresponding to gas-gas, gas-liquid, liquid-liquid, solid-solid, gas-solid equilibrium
- compute accurately chemical reaction constants over a broad range of conditions (temperature, pressure, composition)
- analyze systematically (again by combining the 1st and 2nd law of thermodynamics) processes involving chemical reactions (e.g., in a fuel cell) for the production of work

- Basic concepts and principles. System, environment, interaction, property, work, heat, energy, restraints
- The 1st law of thermodynamics for closed systems and open systems. Applications to steady-state processes, and to processes involving transients
- Reversibility and Entropy: Clausius’ theorem, the 2nd law of thermodynamics for closed and open systems, the entropy balance and applications, power generation and refrigeration cycles
- Mathematical foundation of thermodynamics: the entropy representation, homogeneous functions and the Euler theorem, the Maxwell equations, the Euler equation, the Gibbs-Duhem equation, other representations, Legendre transforms, the Born diagram
- Evaluation of thermodynamic partial derivatives and applications (calculation of the Joule-Thomson coefficient, etc.), thermodynamics of rubber elasticity
- Evaluation of the thermodynamic properties of real substances, the virial, the van der Waals, and the Peng-Robinson equations of state, cubic equations of state, evaluation of changes of thermodynamic properties using equations of state.
- Thermodynamic equilibrium and stability. Criteria for equilibrium, stability of thermodynamic systems.
- Calculation of pure fluid-phase equilibria. Fugacity of a pure gaseous, a pure liquid, and a pure solid phase, computation of vapor pressure from an equation of state, thermodynamic properties of phase transitions (Clausius-Clapeyron equation, Antoine equation, first- and second-order phase transitions)
- Phase equilibrium for multi-component systems: Thermodynamic description of mixtures, criteria for phase equilibrium in multi-component systems, partial molar Gibbs free energy and the generalized Gibbs-Duhem equation, ideal and excess mixing properties.
- Estimation of the Gibbs free energy and fugacity of a component in a mixture. Activity coefficient models. Vapor-liquid equilibrium using activity coefficient or equations of state models, gas-liquid, liquid-liquid, liquid-solid, solid-solid, gas-solid equilibria, osmotic pressure, freezing-point depression
- Combined chemical and phase equilibrium: Balance equations for reacting systems, thermodynamics of mechanical and chemical explosions, production of work, applications to processes such as combustion and explosion, applications to fuel cells.
