THEADSORPTION OF RAREYGASES ON~SOLIDY
In the above discussion we have assumed along with others that benzene is an inert solvent in spite of the gradual accumulation of evidence to the contrary. 41,42 To the extent that H-bonding wi1,h the solvent occurs, not only mill the degree of association of the solute be less but, more importantly, both solvation and orientation of the solvent molecules about the solute will affect the entropy of the system in a more complicated manner. The low solubility of benzimidazole in beiizeiie is probably due to its high degree of association in the solid state but f e v structures of crystals involving N-H---N bonding have been reported. 4 3 (41) L.
