A numerical simulation model has been developed which enables one to examine the effects of surface mass transfer resistance on the evaluation of permeation ( P *), diffusion ( D ), and solubility ( S ) coefficients from unsteady‐state mass transfer experiments as well as the transmission rate. A complementary analytical expression has been developed which validates the numerical model and facilitates the evaluation of the concentration dependence of P *, D , and S from sequential step‐change experiments, under experimental conditions when the surface mass transfer resistance can be neglected. © 2017 Wiley Periodicals, Inc.
