Webprocesses. Out of Onsager’s region, the transport coeﬃcients may depend on the thermody-namic forces and Eqs (2) may loose their validity. This happens when the ﬁrst end/or the second assumption of the Onsager theory [i.e., the above-mentioned assumption 1) end/or assumption 2)] are/is not satisﬁed. WebIn this region, the transport and rate equations are expressed in linear forms, and the Onsager reciprocal relations are valid. Therefore, sometimes this region is called the linear or Onsager region and the formulations are based on linear nonequilibrium thermodynamics theory. csr gyprock locations
