The kinetic-molecular model for condensation flux magnitudes applied to binary mixtures

The kinetic-molecular model (KKM) for calculating the rates of condensation of supersaturated unary vapors has been extended to ideal and nonideal binary vapors by treating such mixtures as pseudovapors with properties assigned according to a linear combination of the properties for the pure components in the vapor phase. The single empirical KMM parameter, the hot-cluster stabilization parameter (SP) was found to vary with vapor composition, with deviations from linearity that could be correlated with cluster compactness; indeed, SP provides a measure of this structural feature.
