Gibbs free eneigy

One can define the Helmholtz free energy F° and the Gibbs free eneigy G° of the interface in a similar fashion ... 

Figure 2.6. Variation of the Gibbs free energy function G and the Gibbs free eneigy change of the reaction AG with extent of reaction for reactions between pure substances, for example, solids or solids and liquids.

If the particle is not too small (see later in this section), the surface free energy of the particle is given by Anr er, where r is the particle radius and a is the surface tension of the bulk material corresponding to a planar surface. The Gibbs free eneigy for the system composed of the vapor and the particle is given by (Frenkel, 1946)...

According to the Gibbs free eneigy values, a dioxane (ld-5d) formation is thermodynamically favorable it slightly increases while the number of alkyl substituents at the double bond grows. Thus, the Gibbs free energy value for ethylene amounts to -7.4 kJ/mol, whereas this value for 2-butene is -35.3 kJ/mol.
