There are Italian editions of books 1 and 4 (although the latter is rather dated). A number of volumes are also available for consultation in the library
of the department.
The dedicated page of the course on the moodle2 platform contains all the teaching material presented during the lectures: presentations in PDF format containing all the derivations illustrated in classroom and a wide selection of solved exercises, example of lab reports, videos of experiments and a large database of quizzes that can be used in preparation for the final written exam.

Lectures with presentations (beamer or powerpoint) Laboratory experiments in which the students (divided into groups of 3-4 people) perform the tasks illustrated during the lectures, under the supervision of the lecturer and the tutor.
For any question you might have, please contact the lecturer by email
The exam consists of a written test and an oral exam, to which the student can have access after passing the written test.
The written test consists of 15 multiple choice exercises (all of equal weight, and generally of a numerical character, 1 correct answer out of 4 possible choices).
The aim is to test the student's ability to apply knowledge and understanding.
The passing grade is greater than or equal to 18/30.
Before attending the oral exam, which serves to test communication skills and theoretical knowledge of the discipline (classical thermodynamics and chemical kinetics), the student must submit the lab reports (just one report per group). The reports will be discussed during the oral examination. The oral exam covers all the topics covered in the course and can include simple derivations of equations / general results discussed during the lectures.
The evaluation grid adopted is as follows:
- Excellent (30 - 30 cum laude): excellent knowledge of the topics, excellent proficiency of the technical language,
excellent analytical ability.
- Very good (27 - 29): good knowledge of the topics, notable fluency in technical language,
good analytical ability.
- Good (24-26): good knowledge of the main topics, fair command of technical language; the
student shows adequate analytical ability.
- Satisfactory (21-23): the student does not show full mastery of the main topics, despite possessing the fundamental knowledge;
language skills are satisfactory and the analytical ability is sufficient.
- Sufficient (18-20): minimal knowledge of the main topics and
technical language, limited analytical ability.
- Insufficient: the student does not have acceptable knowledge of the contents of the
different topics of the program.
Changes to the above guidelines, which could be made to enforce security measures related to the COVID19 emergency, will be notified on the Department's web site.
This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs)
