Speed at which molecules break down using electricity

AI Thread Summary
The breakdown of molecules using electricity is influenced primarily by the applied voltage and current, with voltage needing to be sufficient to separate the molecules and current determining the breakdown rate. The specific molecule in question also plays a crucial role, as different molecules require varying electric fields for effective breakdown. For some molecules, only a few volts per meter are necessary, while others may need megavolts. The discussion highlights the importance of understanding the chemistry involved in electrolysis and molecular interactions. Overall, the effectiveness of the process depends on both the electrical parameters and the nature of the molecules being broken down.

When breaking down a molecule using electricity, what determines how much of the substance is broken down per second. Is it the voltage, current, or something else I'm not thinking of?

It all very much depends upon what molecule you're discussing; this question relates very closely to the Chemistry involved. Some will require an electric field of only a few volts per metre whilst some will require Megavolts per metre.
If you consider the way Oxygen molecules bond to Haemoglobin in the red cells, only a very slight difference in concentration of Oxygen will cause the Oxygen to be held or released. the electrical potentials in each case must be extremely low.
 
I need some suggestion for preparing GATE 2013 Electrical Engg where as I have completed my BE In Electronics and Telecomm.How to prepare for Gate and which reference is to be used.
Thanking you
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
