A model based on the two film approximation is proposed for the description of the kinetics of the hydrogen isotope exchange between CHCl 3 and D 2 O. In this model, details of mass transfer in interfacial region between the two liquid phases are considered and the kinetics of the exchange reaction is quantitatively described without an adjusting parameter. This model is successful in explaining the experimental results obtained with high alkali concentrations, which has not been sufficiently explained in our previous article [M. Iwasaki et al., J. Phys. Chem. , 93, 5139 (1989)]. © 1993 John Wiley & Sons, Inc.
