A dimensionless equation for gas diffusion in microporous media in Knudsen's regime.

both cases, the calculated results agree well with experimental values. Thus, the above inter facial reaction model can be adopted as the most suitable model to express the experimental results. In Fig. 6, values of logk° dnl are plotted against logKdnl for propionic acid and acetic acid systems. The value of rate constant, k°dnl, for each desorption step increases with the equilibrium constant, Kdnl. The linear logarithmic relationships involving the rate constants and equilibrium constants of the same reaction series have been obtained in the homogeneous reaction,2) that is, hydrolysis of ester.
