Chimie physique : équilibre [SCHIB201]

Learning outcomes

Introduce the students to the notions of Physical Chemistry in order to learn and understand: · The composition and internal structure of matter at equilibrium, · The relationships between the structure of matter and its different properties, · The conditions in which any physical and/or chemical transformations can take place.

At the end of the Teaching Unit, students will be able to:

• Rigorously present the formalisms (and demonstrations) of the course, explain their meaning (contextualize them) and specify their conditions of validity;

• Solve problems similar to those treated in tutorials and/or during the course;

• Interpret and/or produce any schema and diagram discussed/detailed during the course;

• Illustrate or propose applications, with examples from the course, of concepts, formalisms, methodologies in physical chemistry;

• Highlight and explain the links between the theoretical course and the practical labs associated with the course.

Content

After the Block 1 General Chemistry course, this first Physical Chemistry course consists of the study of matter at equilibrium seen at the macroscopic scale. It is made up of three parts: · Classical thermodynamics, · Changes of state of pure substances and mixtures as well as chemical equilibria, · Electrochemistry at equilibrium.

Exercises description

Students benefit from tutorials (TD) and practical lab works (TP) sessions. They must prepare the manipulations they are going to perform in the laboratory and are questioned orally at the start of each manipulation. The students then have one week to write a laboratory report that includes a theoretical introduction, the presentation and discussion of the experimental results, a conclusion and bibliographical references. When the report is submitted, its content is discussed and defended with the assistant. The evaluation of the practical work is based on five main learning outcomes:

AA1: Write a theoretical introduction including a description of the concepts, relationships, apparatus and tabulated data useful for understanding the results.

AA2: Correctly process data collected during the practical work with the aim to determine quantities or relationships (applications of relationships between concepts, creation of graphs and data tables).

AA3: Discuss measured or calculated data and compare with tabulated or theoretical data, including consideration of the accuracy of the measuring instruments.

AA4: Correctly present a long report, with the formal quality that complies with the standards of university higher education (spelling, style, syntax, layout, bibliography).

AA5: Orally defend the written report: Answer questions related to concepts, relationships, equipment, measured or calculated data, discussions.

A 6^th learning outcome on the preparation for experimental manipulations is also assessed but in a less systematic way.
