Basic course in reaction thermodynamics


Due to the current long-term unpredictable development of the COVID-19 pandemic, the lecture "Reaction Thermodynamic Fundamentals for Energy Systems" in WS20/21 will be offered online for self-study. The first lecture will be held via Zoom. The dial-in link will be published via Moodle in time before the start. There you will receive all relevant information about the course. Please register to receive current information and lecture material on the Moodle platform.


To begin this course, the thermodynamic basics will be briefly reviewed. The functional relationship between the parameters will be presented, and based on the thermal equation of state of the ideal gas, real gas effects will be presented and discussed. The first and the second laws of thermodynamics will be briefly presented, with which the exergy will be introduced.

Building on these foundations, the real substance behavior, based on the derivation of the real change in enthalpy and the internal energy at state changes compared to the behavior of ideal gas will be presented.


  • Introduction to the thermodynamics of mixtures, ideal mixtures, real mixtures, thermodynamic treatment of mixtures
  • Status variables of chemical reactions, the stoichiometric chemical equation, reaction cycle number, reaction kinetics, equilibrium considerations
  • Reaction enthalpy, absolute enthalpy, temperature dependence of the reaction enthalpy
  • Equilibrium of chemical reactions: Gibbs’ free enthalpy, reaction balance, temperature dependence of the equilibrium constant, exergy of the chemical reaction, introduction of the chemical potential
  • Phase equilibriums of one component systems and ideal mixtures
  • Chemical and phase equilibrium of real material behavior, fugacity
