Eduard-Job-Foundation for Thermo- and Matterdynamics

Georg Job, Regina Rüffler

Physical Chemistry. Part I: Fundamentals of Matterdynamics


The intention of the lecture is to impart the main features of matterdynamics in three parts

  • matterdynamics (in narrower sense) (statics, also referred to as “chemical thermodynamics”)
  • progression of substance changes in time (kinetics)
  • interaction of electric fields (electrochemistry)

and to give at the same time an overview about important branches of physical chemistry. Basic quantities and equations necessary for the qualitative and quantitative description of changes of substances are introduced directly to the reader by using everyday experiences and particulary numerous demonstration experiments. In this way the motivating power of fascinating experiments is utilised, because students often regard physical chemistry as very abstract and not useful for everyday life.

It seems that two thermodynamic quantities are especially difficult to understand: the entropy S and the chemical potential μ. But in fact, both quantities are compatible with an average person´s perception. Therefore, as a fast and easy way, without the frightening mathematical apparatus, both quantities are introduced by a phenomenological definition and direct measuring procedure, in the same way as the basic quantities length, time or weight. The chemical potential has a key position in dealing with chemical problems and starting from this central quantity, it is possible to explore many other fields up to quantum statistics.

A first impression is given by four chapters (pdf) (Chap. 2: Entropy; Chap. 3: Chemical Potential; Chap: 4: Influence of Temperature and Pressure on Chemical Changes; Chap. 5: Mass Action and Concentration Dependence of the Chemical Potential) as example out of the preliminary version of the first part.
