The Free Volume for Rigid Sphere Molecules

摘要: The free volume is calculated for non‐interacting rigid sphere molecules taking into account the exact geometry imposed by face‐centered cubic packing. size and shape are quite different from that of inscribed spheres which correspond to Lennard‐Jones Devonshire approximation. At high densities equation state obtained treatment agrees well with Eyring or equation. When specific greater than twice cube collision diameters, no longer confined cages formed neighboring molecules. these low concept ambiguous. depends upon orientation cells respect lattice positions A particular choice considered leads an at accurate through second virial coefficient. There other shapes orientations would lead equations having this same property.
