Abstract
A recent result, relating the (irreversible) work performed on a syste m during. a non-quasistatic process, to the Helmholtz free energy diff erence between two equilibrium states of the system, is discussed. A p roof of this result is given for the special case when the evolution o f the system in question is modelled by a Langevin equation in configu ration space.
