Academic preconditions:
KE501 Fundamental Chemistry or FF503 and KE523 Physical Chemistry A must be passed, KE521 Chemistry of the elements must have been attended.

Course introduction
The purpose of the course is to carry on the basic concepts of physical chemistry, apply them in a more advanced framework than before and extend them towards non-ideal behavior, both in a theoretical and in an experimental part of the course. The students shall get more familiar with the dependency of the systems on temperature, pressure and composition. The concepts and phenomena of earlier courses (KE523 and KE508) will be taken up and elucidated by calculus exercises. The students will as well apply and train general laboratory techniques including planning of experiments and lab reporting by performing simple exercises in the lab. These comprise basic physico-chemical methods as are calorimetry, vapor pressure measurements, conductivity measurements, quantitative material determination, etc. . The theoretical and practical exercises are chosen such that they do not only serve for repetition but lead into more details within the syllabus of the subject. Moreover, they provide a general introduction and exercise on the analysis and discussion of experimental data in scientific format.

Expected learning outcome
By the end of the course the students shall be able to:

• display a broad insight to the concepts of classical physical chemistry including the established models and methods,
• explain energetic quantities and their combination in the fundamental theorems of thermodynamics,
• derive simple thermodynamic relations that follow directly from the relations derived in the textbook,
• explicate the terms chemical potential and equilibrium, and be capable to use them for the deriving of relations that interrelate the changes in pressure and temperature of pure and mixed phases (phase diagrams),
• derive relations that relate phase equilibrium with concentrations of mixtures (freezing point depression, boiling point increase, osmotic pressure and solubility) and as well the relations describing the properties of liquid mixtures (vapor pressure, laws of Raoult and Henry),
• describe the deviations of real systems from ideal behavior using quantities as compressibility, osmotic coefficients, and activity coefficients, and calculate them either from measured quantities or from tabled data as well as know the options to convert them for simple mixtures (Gibbs-Duhem equation)
• elucidate the term “amphiphile” using a property like surface activity and explain the effect of a surface active material,
• explicate the absorption of material onto surfaces and into interfaces (Langmuir isotherm) and be able to extract the adsorption coefficient from experimental data,
• define specific conductivities, limiting conductivities, ion mobilities and transport numbers. Students shall know Kohlrausch’s law and be able to calculate transport properties of strong electrolytes from tabled data as well as the degree of dissociation of weak electrolytes from conductivity measurements,
• set up mass and charge action equations for an electrolytic process to yield proper Nernst equations,
• work quantitatively, considerate and routinely in a chemical laboratory and be able to judge the quality of experimental data,
• get to be capable of planning and conducting, both autonomously and as well as member of a team, experimental studies on basic physical chemical problems up to writing complete lab work reports
