The Thermodynamics of Chromatography - Interactions Between the Atoms of Hydrogen, Carbon, Chlorine and Bromine and an Exclusively Dispersive Stationary Phase > Experimental Data > Page 38

This linear relationship can be put in the form,


where (f) and (y) are constants.

For the specific  elements examined,



The significance of equation (18) needs to be discussed. When there are no forces between the element and the stationary phase (i.e., (DHo) is zero) the standard entropy is -0.9094. This will be the entropy change that occurs when the element environment changes from a gas to that of a liquid. Thus, (y) represents, the standard phase-transfer entropy.
