WebOct 1, 2001 · The activation energy of isobutane diffusion is also comparable to those obtained from the gas permeation and QENS measurements reported in the literature. Although isobutane has a larger kinetic diameter than n-butane, the diffusivities of isobutane in the membrane and ZSM-5 samples are surprisingly higher than for n-butane. The kinetic theory of gases deals not only with gases in thermodynamic equilibrium, but also very importantly with gases not in thermodynamic equilibrium. This means using Kinetic Theory to consider what are known as "transport properties", such as viscosity, thermal conductivity and mass diffusivity.
