THE DISTRIBUTION OF MOLECULES OVER INDEPENDENT SUB-VOLUMES

Three idealised model probability functions for the distribution of molecules over independent sub-volumes are tested by comparing them with a recent computer simulation of the distribution of methane molecules over the cages in a zeolite cryst. A model system of hard rods moving freely on a line is shown to represent best the effects of the mutual exclusion of molecules that arise from their non-zero size. © 1990.
