Q: What is the n-factor for reduction of chromate(VI) to chromium?

Mridul KumarHere a reaction is given: $$\ce{CrO4^2- -> Cr}$$ I don't know the full reaction, but I made some estimates. One estimate was that on balancing charges we get two electrons on right-hand side. I will consider two different methods that I used for finding $n$-factor: $n$-factor is the number of el...

Q: How to estimate the temperature needed to overcome an activation energy barrier?

Murillo HortolanTrying to elucidate a reaction pathway, I calculated the energies for different transition states possible for that reaction (computational chem. DFT). I found activation free energies ranging from 29 to 39 kcal/mol, and wanted to understand if all those transition states are possible in the reac...

@Hotnitricacid(HNQ) n-factor becomes HNQ. Just another day at Chemistry SE.
