|SCIENTIFIC DISCIPLINARY SECTOR||CHIM/02|
The Course Physical Chemistry 2 with Laboratory is focused on chemical kinetics and electrochemistry. It complete the basic chemical-physical knowledge of materials science students, allowing to approach to the investigation of ì complex chemical systems.
This course is designed to introduce the student to theoretical and practical concepts of the chemical kinetics, catalysis, electrochemistry and electrokinetic. The main concept of applied electrochemistry, gas phase/solution kinetics, homogeneous, heterogeneous, and enzymatic catalysis will be provided. At the end of the course, it is expected that theoretical concepts and experimental skills for the study of time-dependent chemical- physical phenomena will have been acquired.
Background in Mathematics, Physical Chemistry I, General Physics and general Chemistry is recommended
Lectures (32 hours), classroom exercises (15 hours). Laboratory experiences in both electrochemistry and kinetics (20 hours). Classroom attendance is strongly recommended, and it is considered foundamental for attendance in the laboratory course
The detailed program is also available on AULA WEB and it will be discussed with the students during lectures
CHEMICAL KINETICS AND CATALYSIS
Reaction rate and order. Molecularity and reaction mechanism. Series reactions. Parallel reactions. Reversible reactions. Kinetic analysis of experimental data. Dependence of reaction rate on temperature (Arrhenius equation). Theory of chemical reactions (collision theory and transition state theory). Kinetics of Complex Reactions. Catalysis and catalysts. Homogeneous and heterogeneous catalysis. Langmuir isotherm. Enzymatic catalysis.
Principles of electrochemistry: electrical conduction in solution, mobility and transport numbers. Activity and activity coefficients. Electrochemical potential and the Nerst equation. Standard electrode potentials. The electrochemical potential and cells. Electrochemistry and materials. Corrosion phenomena

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 demonstrate good familiarity with the mathematical derivations discussed during the lectures. In addition, during the oral examination, the activity carried out in the laboratory will be discussed.
-) Preparation of the laboratory notebook containing a detailed description of all the activities performed in the laboratory. The laboratory notebook, personally written by each student, must be submitted to the teacher 7 days before the exam.
-) Preparation of the lab reports according to the modalities that will be discussed during the course. The reports, which will be carried out in small groups, must be submitted to the teacher 7 days before the exam.
The oral examination is conducted by two faculty members and it will take at least 45 minutes. The oral exam aims to test the knowledge of the course subject, and the problem-solving ability of the students. The preparation of the laboratory notebook allows to test the capability of the student to describe the experimental activity, selecting qualitatively and quantitatively the key information obtained during experiments. Finally, the preparation of laboratory reports, allows both to test the student's ability to work in a team and to assess his/her ability to critically elaborate the results obtained during experiments.
