Chemistry and Physical Chemistry 2 [ LFSAB1302 ]

The course is articulated around 3 themes : - The second principle of thermodynamics (1.7 ECTS), which allows formalising in a rigorous framework the intuitive notions of order and disorder, of free energy (and its relation with reaction equilibrium), of perfect gases and real gases. The gaseous phase equilibria will be especially considered. - The chemical equilibrium in aqueous phases (1.7 ECTS), which especially well illustrates the power of thermodynamics. To apply to the reaction mechanisms in aqueous media the thermodynamic concepts allowing to understand and to study the phenomena of acid-base equilibrium, of solubility, of chemical precipitation, of redox equilibrium, and of the electrochemical reactions. - The chemical kinetics (1,7 ECTS), which aims at the description of the concepts of the rate of reaction, of order of reaction, of activation energy, and at revealing the molecular origin of these concepts.

Entropy, absolute temperature, variation of entropy associated with chemical reactions, relation between free energy and reaction equilibrium, perfect gases, real gases, equilibrium en gaseous phases, acid-base reactions, neutralisation, buffer solutions, chemical solubility and precipitation, redox equilibrium, and applications for typical electrochemical reactions, cells, electrolysis, corrosion, rate of reaction, order of reaction, activation energy, molecular origin of reaction orders and of chemical equilibrium, Arrhénius relation. The teaching will consists in magistral courses, a problem based learning session, exercices and laboratory under the supervision of tutors aiming at prompting the students toward reasoning approaches allowing him to understand the topic through personal work. The method will favour the active learning processes.
