Learning objectives
The goal of the course is to combine the most significant aspects of chemical thermodynamics with didactic experiments, performed by the students in the laboratory.
Expected learning outcomes
The student becomes familiar with the principles underlying the spontaneous direction of chemical reactions; by experimental measurements he verifies the validity of thermodynamic laws. The student learns further how to treat a series of experimental data and how to prepare a report containing graphs and numerical elaborations. He will be able to work in team with his/her collegues.
Course syllabus
The properties of gases. The kinetic theory of gases. The Maxwell-Boltzman distribution. Real gases. The First Law. Work and heat. Thermochemistry. Heat capacity. The Second Law. Entropy changes of specific processes. The Third Law. Heat engines. The Helmoltz and Gibbs energies. The Gibbs-Helmoltz equation. The chemical potential. The thermodynamic description of mixtures. The Gibbs-Duhem equation. Colligative properties. Physical transformation of pure substances. Phase stability and phase transitions. The Clapeyron e Clausius-Clapeyron equations. Chemical equilibrium. The response of equilibria to pressure and temperature. The van't Hoff equation.
During the Experimental Laboratory physico-chemical parameters are determined (ΔU, ΔH, equilibrium constants, CMC of surfactants) through the elaboration of different measurements (calorimetry, spectrophotometry, conductivity, vapor tension) on the grounds of thermodynamic relations.

Prerequisites for admission
The student should be familiar with derivative and integral calculus. Further he/she should be able to perform calculationd and diagrams by the Program Excel.
Teaching methods
Class room lessons combined with numerical exercises and laboratory experiments performed together with the teacher and the assistants.

Assessement methods and criteria
The assessment method is an oral examination combined with the solution of simple exercises. During the exam the student discusses the laboratory experiments and the thermodynamic principles underlying the experiments.
The final mark is also determined by the evaluation of the Laboratory Relation.
