The freezing of submonolayer krypton adsorbed on graphite is examined within the framework of recently proposed analysis of the nonlinear integral equation that relates the densities of the coexisting nonuniform surface liquid and solid phases. Density changes for freezing of the twohyphen;dimensional fluids were evaluated for various temperatures, liquid state densities, and values of the parameter characterizing the magnitude of the periodic part of the gasndash;solid interaction. It is concluded that the theory gives reasonable results which could be improved if more precise values for the structure factors of the fluid phase were available.
