 The central result of classical nucleation theory is a prediction for the "rate of nucleation" formula_1, in units of (number of events)/(volume·time).For instance, a rate formula_2 in a supersaturated vapor would correspond to an average of 1000 droplets nucleating in a volume of 1 cubic meter in 1 second.The CNT prediction for formula_1 is

where

This expression for the rate can be thought of as a product of two factors
