The phase rule: variance
3. State changes of mixtures
Introduction
Thermodynamics of gas mixtures
Thermodynamics of liquid mixtures: chemical potential of liquids, Raoult's law, Henry's law, chemical activities of solvent and solute
Colligative properties: ebullioscopic elevation, lowering of melting point, osmosis and osmotic pressure.
Solubility
Coefficient of partition

Stability of solutions
Liquid-vapor, liquid-solid binary systems
5. Diagram of the phases of ternary systems
6. Chemical equilibria

Learning outcomes of the learning unit

This course of scond year deepens the subjects seen in the 1st year course of General Chemistry and opens to more conceptual subjects.
It covers the following subjects:
Thermodynamics: introduction of concepts and quantities
Change of state of pure and mixed substances.
Phase diagram of simple, binary and ternary systems.

Prerequisite knowledge and skills

Good knowledge of general chemistry (fisrt year)

Planned learning activities and teaching methods

Mode of delivery (face to face, distance learning, hybrid learning)

Thermodynamic part: classroom teaching
20h of theory, 20h of sessions of exercice and 15h of laboratory

Organisational adjustments related to the current health context

Given the evolution of the health context, the theoretical courses will be given in virtual mode from October 19th and until further notice.
Students will have access to:
- commented powerpoints
- to an eCampus forum for asking questions
- live question-answer sessions
The exercice sessions will be given in virtual mode from October 26 and until further notice. Students will have access to:
- the resolutions of commented exercises (CamDoc)
- to an eCampus forum for asking questions
The practical work sessions are canceled from 26/10, and until new information. Appropriate reflection works will be prepared by the assistants to replace the classic guided work sessions as best they can.

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

The final evaluation concerns all the parts of the course (theory, problems, laboratory)
The successful completion of the course will be awarded to any student with a minimum overall score of 10,00 / 20.
