What are the physical meanings of lower and higher values of activation energy in proton conduction phenomenon?

04 August 2017 1 6K Report

We determine the activation energy from Arrhenius Plot. If its value exists between 0.1 - 0.4 then proton conduction follows Grothhus mechanism and 0.5-0.9 leads to Vehicular mechanism.

Javier Rivera De la Rosa

low activation energies (< 10 000 cal/mol) are for mass transport phenomena and higher for chemical reactions.

Why don't d-orbitals split themselves, why does it take a ligand? why don't protons from ligand repel nucleus split d-orbitals?

why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the...

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
