The change in Gibbs free energy within the 2LiF− \({{\hbox {BeF}}_{2}}\) and LiF–NaF–KF system is closely tied to the van der Waals radius. The radius for each noble gas in the system involves an evaluation of the two key components of Gibbs free energy analysis: volume energy and surface energy. Volume energy gives the potential for a phase transition—either evaporation or condensation—to occur. Whereas surface energy quantifies the energy necessary for interface formation. The surface and volume energies are clearly shown along with the cumulative sum.
