Abstract

The correlation equation Dc,f,vapΨo = i + f *N have been used for the description of thermodynamic functions DΨo of free energy, heat, entropy and heat capacity of the combustion, formation and vaporization processes for alkanes of the different space structure. The i and f are stoichiometric coefficients; they have been determined for 34 equations, which have described the processes in condensed and gaseous phases. The consideration of all presented data allows to draw the main essential conclusion: the all mentioned above functions depend on number of valence electrons in the researched substances.The heat capacities depend on number of valence electrons too.  

Alkanes free energy of combustion free energy of formation the heat of combustion the heat of formation the heat of vaporization entropy heat of capacity
