Objectives and Contextualisation

The student keeps progressing on its Physical Chemistry education with the goal of visiting the full extension of issues that make this subject total content, the Physical Chemistry. After the microscopic approximation involved in Quantum Chemistry, the macroscopic approximation to Thermodynamics and Kinetics (with minor microscopic hints), this subject will be dealing – as its title indicates- with Transport Phenomena and Surface Phenomena. Thus, gases kinetic theory, the different types of solution transport (diffusion, migration and convection), the existence and definition of interphases, and their application to kinetics (heterogeneous catalysis) and electrochemistry (double layers), will be studied. Electrochemistry, that can also be visualized as a surface phenomenon, will be treated from a thermodynamic and kinetic point of view. The course will end up with the study of some macromolecules: colloids and polymers, hence closing with all these contents the full view of the Physical Chemistry field.

Methodology

The acquisition of knowledge will be done through the use of theoretical classes and problems.
										
											
										
											Theoretical classes (lectures with a blackboard and / or with the help of audiovisual media) in which the basic concepts will be introduced in order to understand the fundamental and applied aspects of this subject
										
											
										
											Classes of problems (with more participation of the students) in which the methodology to solve quantitative numerical questions will be indicated.

Assessment

In this half face-to-face year :

Classroom written exams  (50% of the final mark). Accordingly to the academic calendar 2 exams will be carried out. A mark equal or above to 3,5 (out of 10) is required in order to be able to add it to the remaining 50% of the marks (classroom exercises). If the mark is below 3,5, the student will have to take the second-chance exam, that will include the whole course, in order to pass the subject.

Classroom exercises fulfillment (50% of the marks). The culmination of these exercises (problem solution, test,..)  is mandatory and is not subjected second-chance attempts.

In order to participate in the second-chance exam the students have to sit for the two previous written exams  and for 75% of the classroom exercises.

In case the Covid 19 situation forces the classroom written exams to change to on-line exams, the marks percentage distribution would change: 30 % for the on-line written exams, and 70% for the “classroom” exercises (either face-to-face or on-line).
