Résumé :

The thermodynamics of irreversible phenomena, based mainly on the concept of entropy production, leads to linear and homogeneous relations between affinities and reaction rates close to equilibrium. These laws have been verified experimentally in the case of the catalytic reaction of the hydrogenation of benzene and the inverse reaction of the dehydrogenation of cyclohexane. The method used for measuring rates is the dynamic method of high flow rates. The domain of validity of these laws is discussed. In a quasi-steady state, particularly simple relations are established.
