General description A Química Física é o estudo dos principios físicos fundamentais que gobernan as propiedades e o comportamento dos sistemas químicos. Un sistema químico pode estudarse dende un punto de vista microscópico ou macroscópico. Neste curso de Química Física introdúcese a metodoloxía do estudo macroscópico de equilibrio (Termodinámica Química)
Os contidos que se imparten nesta asignatura constituen os fundamentos teóricos imprescindibles para as seguintes asignaturas de Química Física e un marco de referencia para todas as demáis ramas da Química que, necesariamente, aplican boa parte dos conceptos estudiados nesta asignatura no desenvolvemento dos seus programas específicos.

Contents
Topic Sub-topic
1. Introduction to Chemical Thermodynamics. Previous concepts and mathematical properties
2. The principles of Thermodynamics. First law: internal energy, enthalpy, heat capacities. Second law: entropy, calculating the entropy change in simple systems.

Applications: thermodynamic equations of state, the difference between the heat capacities, the Joule-Thomson coefficient.
4. Thermodynamics standard reaction functions Standard enthalpy: Kirchhoff's and Hess's law. Standard Entropy: the third law of thermodynamics, conventional entropy determination. Standard Gibbs energy. Using thermodynamic tables.
5. Thermodynamics of systems of variable composition The chemical potential. Partial molar properties. Material equilibrium conditions: phase equilibrium and chemical equilibrium.
6. Gas state thermodynamics The ideal gas: chemical potential and properties, ideal gas mixture. Real gases: equation of state and fugacity, fugacity calculation.
7.Phase equilibria in systems of one component The phase rule. Phase diagram for one-component systems. Clapeyron and Clausius-Clapeyron equations. Classification of phase transitions.
8. Solutions Ideal solution: Raoult's Law. Ideally dilute solution: Henry's Law. Mixing functions. Nonideal solutions of nonelectrolytes: activity and activity coefficients, the Gibbs-Duhem equation, excess functions. Solutions of electrolytes: the activity coefficient of ionic species.
9. Phase equilibria in multicomponent systems Liquid-vapor equilibrium: ideal solution at constant T and P constant, fractional distillation, azeotropic mixtures. Liquid-liquid equilibrium: miscibility. Solid-liquid equilibrium: temperature-composition diagrams, simple eutectic, compound formation with congruent and incongruent melting, thermal analysis. Solution-crystalline solid equilibrium. Colligative properties: freezing point depression, boiling point elevation, osmotic pressure, vapor-pressure lowering. Nernst's distribution law.
10. Chemical equilibrium Chemical equilibrium in gas mixtures: the equilibrium constant, changes in chemical equilibrium-Le Chatelier's principle. Chemical equilibrium in solution. Chemical equilibrium with pure solids and liquids.
11. Surface thermodynamics The interface: surface tension. Curved interfaces: capillary rise. Adsorption on solid: physisorption and chemisorption, adsorption isotherms.

Methodologies
Methodologies Description
Guest lecture / keynote speech Lectures, where the theoretical concepts will be introduced
Problem solving Seminars in small groups where it will be shown the application of the theoretical contents from the lectures into problem solving
ICT practicals Practical exercises where students will solve complex problems using computer programs
Critical bibliographical Students will be taught to do bibliographic search. They will be asked to perform searches about topics related with the subject.
Reading of papers related with topics from the subject will be also proposed
Mixed objective/subjective test Students will be asked to solve a problem which combines the theoretical concepts and their application. Resolution will be achieved jointly with lecturer's guidance
Case study A real case study, directly related with the application of Thermodynamics, will be posed to the students. Students will be asked explaining this case study using the basis of Thermodynamics and they will be asked proposing possible alternatives. Solution of the case study could be achieved with bibliographic search or even completed with simple experiments in the laboratory. Work will be developed in groups
Mixed objective/subjective test A final test will be done at the end of the semester. Students will be asked solving problems on their own

Assessment comments

The student who engages in any of the activities will be considered to have attended on the subject at the time of the final mark. The above marks rating corresponds to January (first opportunity).

To facilitate completion of the course, there will be an extraordinary, optional test. To carry out this test regular attendance at lectures and seminars in small groups is required and also participation in all the other methodologies proposed. This optional test will score 7 out of 10 to calculate the final mark. Those students achieving a final mark of 5 out of 10 would not require to attend to the final test. In any case, students wishing to improve their final mark may be re-examined of the entire matter in the final test. The date of this extraordinary test shall be established by consensus among students, teachers and coordinator.

The rating of the second opportunity will be made only with a final test, scoring 10 out of 10.

Honors grade: priority is given in the first opportunity. Honors grade may only be granted in the second opportunity if their number have not be exhausted in the first opportunity final qualifications. Should it be more candidates to honors grade than honors available, allocation will be done through a extraordinary exam.

Scheduled activities dates:

1st activity: to be established

2nd activity: to be established

3rd activity: to be established

Final testing will take place at the following dates and times(pending approval by the Faculty Board):

-First Opportunity: Check the official dates approved by the Faculty Board

-Second Opportunity: Check the official dates approved by the Faculty Board
