Abstract
A fundamental investigation of the departure from equilibrium in steadyβstate phase transitions has been made in terms of irreversible thermodynamics and absolute rate theory. The present status of the concept of accommodation coefficients was reviewed and hypotheses were advanced for the reconciliation of opposing viewpoints. Formulas for the magnitude of the departure from equilibrium were derived for singleβ and multicomponent systems. The deviation from equilibrium appeared to be small for ordinary rates of phase change, but interpretation of the available data was hampered by lack of a detailed molecular picture of the phaseβchange process.

The steady-state serum kinetics of zotepine, an antipsychotic drug, were studied in 59 psychiatric in-patients receiving 50-500 mg/day (mean 215 mg/day) of the drug. There was a 26-fold inter-individual variation in the concentration/ dose ratios (C/D ratios: ng/ml/mg/kg), which ranged from 2.4 to 6
The theory of the steady-state kinetics of irreversible enzyme-catalyzed homopolpmerization and copolymerization on primers has been developed. The rate law for homopolymerization is of the Michaelis-Menten form, but the kinetic parameters depend on primer concentration. Copolymerization has been tr
