Is two activation energies possible (Arrhenius plot) for an ionic liquid?

Using the Arrhenius equation to adjust the self-diffusion of an ionic liquid, I found two linear regions (two activation energies, “dynamic crossover effect” see figure). Is this a correct...

What is the physical meaning for ionicity values (Λimp / Λnmr) greater than 1.0?

I found ionicity values (Λimp / Λnmr) greater than 1.0 for some ionic liquids in aqueous solutions. PS: I found negative values for the deviation (Δ) of the Nernst-Einstein equation.
