The second entropy theory for nonequilibrium thermodynamics is extended to the nonlinear regime
and to systems of mixed parity even and odd functions of molecular velocities . The steady state
phase space probability density is given for systems of mixed parity. The nonlinear transport matrix
is obtained and it is shown to yield the analog of the linear Onsager-Casimir reciprocal relations. Its
asymmetric part contributes to the flux and to the production of second entropy. The nonlinear
transport matrix is not simply expressible as a Green-Kubo fluctuation equilibrium time correlation
function. However, here the first nonlinear correction to the transport coefficient is given explicitly
as a type of the Green-Kubo equilibrium time correlation function. The theory is illustrated by
application to chemical kinetics. 2007 American Institute of Physics. DOI: 10.1063/1.2745300
