|SCIENTIFIC DISCIPLINARY SECTOR||CHIM/02|
The Course Physical Chemistry is focused on thermodynamics and chemical kinetics. It complete the basic chemical-physical knowledge of materials science students, allowing to approach to the investigation of complex chemical and biochemical systems.
Acquire methodological rigor and mathematical formalism to interpret and describe the fundamental phenomena that underlie the chemical-physical systems. Particular attention will be paid to the description and understanding of the energy profile of chemical systems as well as to the physical-chemical phenomena as a function of time.
Background in Mathematics, General Physics and General Chemistry is recommended.
Lectures (48 hours), Classroom attendance is strongly recommended.
The detailed program is also available on AULA WEB and it will be discussed with the students during lectures

The examination test consists of
- Oral examination will cover both theoretical aspects of the course and the resolution of exercises. The student must demonstrate understanding of main chemical-physical concepts and he/she must show good familiarity with the mathematical derivations discussed during the lectures.
- Preparation of a short presentation (also with ppt support) on a topic discussed during the course.
Oral examination in which the student answers questions about the topics covered in class;
notably, for the thermodynamics he must prove the ability to set a problem.
