Prerequisites

It is advisory to have completed "Fonaments de Química", "Química Quàntica" and "Termodinàmica i Cinètica"


Objectives and Contextualisation

The student continues to advance in his/her training in Physical Chemistry with the aim of completing his/her training in this subject. After the microscopic approach in Quantum Chemistry and the macroscopic approach in Thermodynamics and Kinetics (with brief microscopic notes), in this subject - as its title indicates - Transport Phenomena and Surface Phenomena will be studied. The Kinetic Theory of Gases will serve as a basis for the study of transport phenomena in the gas phase. Next, the study of electrolyte solutions allows us to address transport phenomena in the liquid phase. Regarding surface phenomena, we will focus on those that take place at the liquid-gas, solid-liquid and solid-gas interfaces. Knowledge in Thermodynamics and Kinetics will be used to address them, with special emphasis on the study of adsorption, both in gas-solid and solution-solid interfaces, and Heterogeneous Catalysis. Electrochemistry, which can also be visualized as a surface phenomenon, will be studied from a thermodynamic and kinetic point of view. The course will end with the introduction of colloids and macromolecules from the point of view of Physical Chemistry.

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  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.

The lecturers will dedicate approximately 15 minutes of a class to allow the students to fill the "Teaching Activity and Subject or Module Assessment" survey.


Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Continued avaluation


Exams: Two partial exams (P1 and P2) will be held throughout the course. All exams will be graded between 0 and 10.
Follow-up work: A series of follow-up tests will be carried out throughout the course. The set of tests corresponding to each partial S1 and S2 will have a grade between 0 and 10. The follow-up test will not be repeated due to the student's absence if this is not documented in a valid form (official medical report,... )


Qualifications: To pass the subject per course, you must obtain a final grade (NFC) greater than or equal to 5.0 and obtain a grade greater than or equal to 3.5 in each of the partial exams. Follow-up tests (S) will have a weight of 20% and the grade of the partial exam (P) 80%
NFC = (0.1 S1 + 0.4 P1) + (0.1 S2 + 0.4 P2) = 0.1 (S1 + S2) + 0.4 (P1 + P2)


Students who do not pass the course by course (continuous assessment) and students who want to improve their course grade
Students who do not pass the subject per course, in accordance with the previous continuous assessment scheme or who wish to improve their qualification, may sit the two remedial exams for partials P1 and P2.
To take part in the recovery, students must have previously participated in the two written tests and 75% of the classroom work
When the student takes a make-up exam, the grade Pi will be that of the make-up exam, if this is higher than the one obtained in the corresponding exam during the course. If the mark obtained in the make-up exam is lower than the one obtained during the course, the grade Pi will be the average of the make-up grade and the exam grade taken during the course. S tracking notes are not refundable.
To pass the subject with recovery, the student must meet the same requirements as to pass the subject by course.

 

If the student has been evaluated on only 25% or less of the tests, the final grade will be NOT EVALUABLE.

 

Unique assessment

Exams: A final test that will consist of an examination of the entire syllabus of the subject to be carried out on the day on which the students of the continuous assessment take the second part exam, P2. The exam will be scored with a grade between 0 and 10.

Qualifications:The student's grade will be the grade of this test. To pass the subject per course, a grade greater than or equal to 5.0 must be obtained.

Students who do not pass the subject per year.
If the final grade does not reach 5.0 the student has another chance to pass the subject through the resit exam.
The student's grade will be the grade of this test.
To pass the subject with recovery, the student must meet the same requirements as to pass the subject by course.
