Hi, can anyone explain the mathematical proof of the Grunberg-Nissan equation:
ln(η) = Σ[xi*ln(ηi)]
where η is dynamic viscosity, x is mole fraction, and i denotes each individual substance in the mixture? Thanks!

Syki:

Your equation does not make sense. I think it is because you are not formatting your fonts and font sizes correctly.

Are you referring to the attached?

Yes, exactly! Sorry, I'm not very good with transcribing equations into html. And actually, it appears I meant the Arrhenius equation.
