Nonlinear flux-force relations and equipartition theorems for the state of minimum entropy production

We explain that the path of minimum entropy production in a system with nonlinear flux-force relations, which do not depend explicitly on the state variables of the system, can be characterised by equipartition of driving forces and equipartition of entropy production. The explanation is based on an optimal control theory formulation of the optimisation problem. The finding helps explaining recent numerical observations on the second law optimal state of chemical reactions.
