At the same temperature, k〓 in the reversed micelles was always less than k＇〓 in the buffer. According to the thermodynamic analysis for inactivation of penicillin amidase in the reversed micelles, the free energy of activation was increased by 2. 71%, while the entropies and enthalpies of activation were decreased, corresponding to 63. 9% and 76. 9% of that in pure buffer respectively.

The coexistence curves and light scattering data for a critical solution of benzonitrile + octane have been reported. The critical exponents relating to the difference in the density variables between two coexisting phasesβ, the osmotic compressibilityγ, and the correlation length v have been deduced and the values were consistent with the 3D-Ising value in the range close to the critical point. The experimental results of the coexistence curves have also been analyzed to examine the Wegner correction terms and the behavior of the diameter of the coexistence curves.
