... to be an activated process. Activation energies for diffusion through the silica membrane calculated from the slopes of Arrhenius plots of the permeation data ranged from 4.61 10 14.0 kcal/mole and correlate well with the kinetic diameter of the penetrants. Large separation factors were obtained for the penetrants...
