Abstract. Generalizations of Onsager reciprocity relations are established
for the nonlinear response coefficients of ballistic transport in the effusion of
gaseous mixtures. These generalizations, which have been established on the
basis of the fluctuation theorem for the currents, are here considered for mass
separation by effusion. In this kinetic process, the mean values of the currents
depend nonlinearly on the affinities or thermodynamic forces controlling the
