Learning Goals

Understanding of the key concepts and the language and machinery of classical chemical thermodynamics. Thermodynamical approach to problems in physical processes, phase transitions, mixtures and chemical equilibria.

Students should understand the key concepts of chemical thermodynamics and use it to solve problems and to calculate relevant quantities in physical transformations (temperature / pressure / volume changes) of mixtures and pure substances, phase transformations and chemical or electrochemical equilibrium processes


The properties of gases: the perfect gas, real gases, equations of state, the principle of corresponding states.
Key concepts in thermodynamics. First law of thermodynamics. Thermochemistry.
Spontaneous change and entropy. The second law of thermodynamics. Gibbs energy. Maxwell equations. Chemical potential. Fugacity. Phase transitions and phase diagram of pure substances.
The properties of mixtures: ideal and real mixtures, the activity, colligative properties, phase diagrams of mixtures.
Application to chemical equilibria. Relationship between the equilibrium composition and the thermodynamic functions. The response of equilibria to the conditions.
Equilibrium electrochemistry. Ionic activities. Debye-Huckel law. Half-reactions and electrodes. The Nernst equation. Standard potentials. Solubility constants.

Teaching Methods

The teaching / learning is based in the individual work of students, supported by recommended bibliography and notes taken by the students either during classes or through individual research. In the lectures the theory will be exposed, commented and discussed with the students. In theoretical-practical classes, the subjects developed in the lectures are illustrated with problems of practical examples.

The evaluation is carried out by the realization of 2 tests (one for the first half of the semester and the other for the second half) and/or one final exam.
