Desorption times for gas-solid systems with localized or mobile physisorption are calculated with the desorption energy supplied by the surface phonon modes of a semi-infinite elastic solid. They are shorter by a factor 2 to 3 than those calculated using bulk phonons. A surface Debye temperature is deduced that is about .7 to .8 of the bulk Debye temperature.
