In the absence of foreign nucleants, phase transition from vapor to liquid is blocked by a free-energy barrier implicit in the appearance of new surface when embryos of the new phase start to form. Drawing upon thermodynamic relationships discussed in Part I, Part II here summarizes the kinetics of the homogeneous nucleation process for the case of the vapor-to-liquid phase transition. Emphasis is placed upon physical interpretation of the mathematical model used to obtain a nucleation rate equation for the unbalanced steady-state case.
