where ∆𝐻 and ∆𝑆 are the changes in molar enthalpy and entropy of the dispersion process, respectively. The temperature 𝑇 = 303 K and the gas constant 𝑅 = 8.314 J • mol • K . The consolidation of Equation 3 and 4 (i.e., 𝑘 ≅ -1/𝑅𝑇) reveals that the dispersion enthalpy is close to the interaction energy (𝐸 NC ):
