| Course contents :
| The subjects teached in this course are : Basic definitions in thermodynamics:systems,variables and state functions. Reversible and irreversible transfer of heat and work ( PdV, mechanical ,useful ). Internal energy and enthalpy : microscopic components . First principle : total energy conservation; application to isolated, closed and adiabatic systems. Compression and expansion ( isothermal or adiabatic ) of perfect and Van der Waals gases. Spontaneity and probability of existence of a thermodynamic state . Entropy : its statistical meaning . Entropy and second principle: application to isolated, closed and adiabatic systems. Criterium for spontaneous evolution or equilibrium.Clausius inequality ; irreversible creation of entropy. Calculus of entropy variation in a few reversible and irreversible processes. Thermodynamic cycles ( direct and reverse Carnot ). Absolute entropy and third principle.Entropy variation with temperature and in phases transformations. Standard entropy of a chemical reaction . Free enthalpy : G . Criterium for spontaneous evolution or equilibrium with regard to G . Combination of both first and second principles:relation between the G variation and useful work. G variation in a chemical reaction. Thermodynamical treatment of the chemical equilibrium.Calculus of the equilibrium constant. Thermodynamics of electrochemical cells . Microscopic approach of chemical thermodynamics; the components of molar heat capacity. The Boltzmann law . The chemical potential and the physicochemical equilibria . The phases transformations. The Gibbs theorem . Phase diagrams of pure substances , binary and ternary mixtures ( distillation, eutectic, peritectic,azeotrope, solubility ..). The colligative properties. | |

| Course objective :
| Course CHIM0270-1 introduces the basic concepts of equilibrium thermodynamics and applies them to chemical thermodynamics ( study of various physicochemical equilibria ) and to the study of phase transformations . Theoretical principles of " engineering thermodynamics" are also examined. | |
|  | | |
| Prerequisites :
| Knowledge of physics, chemistry, mathematics teached during the first year of Bachelor in Sciences of the Engineer. | |
|  | | |
| Workshops :
| No laboratory but a lot of exercices sessions ( 25 h ) in which theory is illustrated by solving various probems with the students. | |
|  | | |
| Organization :
| The course ( total of 60 h : 35h of theory and 25 h of exercices ) includes two parts : The first is teached by J.Marien ( 25+20 h ) and concerns essentially the basic concepts of reversible thermodynamics ; the three principles are teached and applied to chemical thermodynamics and conversion of heat into work.
The second part is given by E.DePauw ( 10+5 h ) and treats essentially of the chemical potential and its application in the study of phases transformations. | |
|  | | |
| Written notes :
| The main support consists of two syllabi : a) one is relative to the first part of the course teached by J.Marien ( " Eléments de thermodynamique":Editions de l'U.Lg. ) b) Another syllabus concerns the second part of the course teached by E.DePauw ( it is the same as the one used in first year of Bachelor )
A series of exercices ( with solutions ) can be found on intranet ( portail étudiants de l'U.Lg. ) . | |
|  | | |
| Assessment :
| In january , there will be a single written examination turning on both parts of the course. | |
