Generally, in binary liquid mixtures we found that weak similarity between the viscosity Arrhenius activation energy (Ea) and the enthalpy of mixtures (Delta H). It seem to be they have common features. Are there any interpretations?

I am not a physical chemist in the strict sense of the world, therefore I cannot save you the effort to understand the related articles in more detail. My impression is, however, that the quoted articles contain the necessary information - at least for binary metal mixtures, but the thermodynamic approach seems to be general enough. Good luck!
