Kinetics of step-wise micelle association
During the last few years, the kinetics of micelle association and dissociation in surfactant solutions have been studied experimentally with various techniques. The degree of association is typically of the order of 100, which requires either that drastically simplified assumptions be made in treating the kinetics, or, that a perspicuous method be found for its handling. First, the kinetic equation is put into a form which suggests an analogy with heat conduction (diffusion, etc.) and identifies the proper rate-limiting quantities. A treatment of the relaxation process at very small deviations from equilibrium is given and the results compared with existing experimental results. The treatment is then extended to larger deviations from equilibrium and a plausible explanation given of the apparent linearity still exhibited by the process. Finally, the process of rearrangement among the abundant micelles is treated by approximating the kinetic equations by a partial differential equation. (30 refs.)
