摘要：

Thermodynamics of irreversible process offers linear expressions among physical quantities when there are physical-chemistry changes in the systems close to equilibrium, which has been extended to the systems far from equilibrium, and a uniform nonlinear chemical reaction rate equation was established to describe chemical reaction rate, that is in general far from equilibrium in discontinuous system, in which exist interface and chemical reactions. Finally, it was applied to manganese oxide reduction reaction and obtained a third-order expression [GRAPHICS] = 3.91 X 10(-6) ((a) over cap)/(T) + 3.09 x 10(-7)(((a) over cap)/(T))(2) + 6.55 x 10(-9) (((a) over cap)/(T))(3), T T which well conforms to the experimental data. The thermodynamics of irreversible process after considering the high-order term can be applied to slag-metal reacting systems far from equilibrium.
