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 a CD.ROM which can be downloaded from the W.W.W. site of the A.E.E.S. ) . |
|
| Assessment : | In january , there will be a single written examination turning on both parts of the course. |
