To study the thermodynamics of open or variable-composition systems with reference to the specifics of ideal systems.
To study the thermodynamics of open or variable-composition systems with reference to the specifics of ideal systems. In particular, the course will furnish the means of determining thermodynamic properties, beginning with volumetric data, and calculating the chemical equilibrium among phases and in reacting systems to be utilised in the study of process engineering systems. The transversal skills in terms of applying knowledge and understanding will be acquired through numerical exercises to be carried out in a group and the use of ICT tools. Communication skills will be encouraged by the proposal to carried out a video on chemical thermodynamic applications to be evaluated during the examination.
Organisation. The course consists of about 35 hours of lessons and 25 hours of practical work conducted in the classroom.
Program. First and second laws of thermodynamics (summary). Thermodynamic functions and chemical potential. Gibbs Duhem equation. Molar, partial molar and mixing properties.

Subcritical and supercritical components: Raoult and Henry laws. Some numerical examples. Phase equilibrium diagrams for ideal binary systems and their deviations.

First semester of academic year: For timetables, please visit the Polytechnic School site.
Examination. A written and an oral exam.
The student's assessment involves an oral test in which three questions are asked about the topics presented in the lesson and the numerical exercises performed independently by the student are discussed . A question will be on the basics of distillation. The student will have to demonstrate how to set and numerically solve the calculation of phase and reaction equilibrium for ideal binary or multicomponent systems and calculate the thermodynamic properties of ideal pure or mixed components.
Prerequisites. It is anticipated that students will have a solid grounding in mathematical analysis, physics and chemistry to be able to deal with the subject matter, but no formal prerequisite is required.
