On the Kinetics of Evaporation [PDF]
The Journal of Physical Chemistry, 1952 The kinetics of evaporation of liquids has been reconsidered from the point of view of classical kinetic reactions and also by application of the theory of absolute reaction rates. It is shown that evaporation treated as a unimolecular rate process, with a rate proportional to the surface concentration of energetic molecules, leads to the Knudsen ...
