  • Learning outcomes of the curricular uni

    1. Solve and analyze theoretical physical chemistry subjects, including equilibrium thermodynamics and interfaces.

    2. Evaluate and understand reactions kinetics, adsorption processes and ion movement.

    3. Correlate macroscopic with microscopic properties, in particular with macromolecules, colloids, polymers and other materials.

    4. Integrate the concepts and illustrate them with real systems. Simultaneously apply the knowledge to solve practical problems.

    5. Apply theoretical concepts to illustrative laboratory work, data treatment, discussion and presentation in written report.

  • Syllabus

    1. State Equations (perfect gases and real gases). Partial pressures. Solubility of gases in liquids. Henry's Law. Raoult's law. Solubility of volatile liquids.

    2. Work and heat. 1st Law of Thermodynamics. Enthalpies. Thermochemistry. Entropy and the 2nd law of thermodynamics. Calorimetry. Gibbs energy.

    3. Phase changes. Liquid-vapor, solid-liquid and solid-vapor Equilibria. Phase diagrams. Colligative properties of diluted solutions.

    4. Transport Properties. Ionic conductivity. Electrolytes (strong and weak). Ionic strength and activity coefficients.

    5. Chemical kinetics. Rate ​​laws. Arrhenius equation. Mechanisms and reactions dynamics. Homogeneous catalysis.

    6. Solid surfaces processes o: adsorption; isotherms; Langmuir equation; adsorption kinetics.

    7. Macromolecules, aggregates, colloids and surfactants. Surface tension and micelles.

  • Demonstration of the syllabus coherence with the curricular unit's objectives

    The proposed syllabus are fundamental concepts of Physical Chemistry framed in the context of Life Sciences. Apart from its assimilation is also intended to promote a vision applied these concepts, so the theoretical exposition is accompanied by the resolution of numerical exercises, examples of applications and practical work.

     

  • Teaching methodologies (including evaluation)

    Classes are taught using slides prepared by the teacher in advance and made available to students through the Moodle platform. The oral exposition is accompanied with illustrative examples and discussion of actual manifestations of physical and chemical phenomena. In theoretical-practical classes illustrative numerical problems of are executed.

    In practical / laboratory classes (mandatory presence) 5 experimental works are performed.

    The experimental work is evaluated based on questionnaires and a report of one of the experiments giving rise to a practice note (NP).

    Continuous assessment:

    Two tests (T1 and T2) 2 hours: T1> = 7.5, T2> = 7.5

    NT = (T1 + T2) / 2 : NT> = 9.5

    Final Grade = 0.25 NP + NT 0.75

    Assessment by examination:

    Written test with a duration of 2.5 h

    Final exam (EF): EF> = 9.5

    Final Note = 0.25 NP + 0.75 EF

  • Demonstration of the coherence between the teaching methodologies and the learning outcomes

    In the preparation of the slides used in the classroom several bibliographical sources, including books available in the school library (which can be consulted and requested by students) are used. This material is made ​​available in advance to the students by computer and thus the student can follow the lesson with printed material (or through your PC or tablet), making their own study notes.

    Also available are additional study sources as educational articles and links to websites that show illustrative experiences and physical-chemical phenomena videos. These supplementary materials can be viewed and discussed during class in order to increase interactivity.

    The resolution of numerical exercises is also an important tool for the understanding and application of the concepts taught laws and models. Apart from quick application exercises at the end of each chapter complex conceptual and numerical problems are resolved.

    The practice component completes the formation. Laboratory work help solidify theoretical concepts through experimentation. The proposed experiments try to cover as much as possible the theoretical content taught.
