Physical Chemistry II and Laboratory A - LModule Physical Chemistry II and laboratory (Module 2)
Academic Year 2023/2024 - Teacher: GRAZIA MARIA LUCIA MESSINAExpected Learning Outcomes
The course's main objective is to provide to the student with specific knowledge in the field of Physical Chemistry
In particular, the student is expected to develop base theoretical knowledge in Physical Chemistry and to be able to apply it practically. This goal will be obtained via various laboratory experiences.
The course contributes to the following transversal skills:
Knowledge and understanding: develop the ability to reason inductively and deductively and the understanding of chemical bonding, molecular spectroscopy and chemical kinetics.
Ability to apply knowledge: being able to apply the knowledge acquired to describe the electronic structure and geometry of molecules rationally; being able to study from a theoretical and experimental point of view the kinetics of chemical reactions.
Judgment autonomy: develop the capacity for critical reasoning and be able to correlate theoretical models to the behavior of molecules
Communication skills: being able to demonstrate the full understanding of matter with properties of language and scientific rigor.
Learning Skills: Demonstrate that you have developed good learning and in-depth skills to understand chemical-physical phenomena and processes
Course Structure
The course is co-taught with Dr. Ruffino and Dr Auditore.
The course will consist of
- Class lectures to introduce laboratory experiences
- Laboratory experiences
- PC exercises for the analysis and the interpretation of experimental data
Required Prerequisites

Learning Assessment
Learning Assessment Procedures
The exam includes a pre-selective written test not preclusive, to evaluate the acquisition of the minimum basic concepts concerning the three sections of the program, and the ability to apply them to the resolution of simple problems, of a type similar to those taken during the course. It is not recommended to take the oral test if in the pre-selective test you have obtained a score below 15/30. The oral exam will focus both on the discussion of a laboratory experience and on the topics of the theoretical course. The final grade will take into account both the outcome of the oral exam and the laboratory reports.
Reports are required on all the experiences carried out in the laboratory, to be sent to the teacher electronically (in word or pdf format) at least 15 days before the date chosen to take the exam.
Should the Covid-19 emergency require it, the procedures for carrying out the examination may be modified, in accordance with the provisions of the academic authorities.
Examples of frequently asked questions and / or exercises
- Describe the laboratory procedures for verifying Stern Volmer’s law
- What is the relationship between the wettability of the surface and its free energy?
- What is a permitted transition?
- Describe the trend of the absorption spectrum in the visible part of I2 and give reasons for this theoretically.
