Hi, I was wondering what effects pressures (>100bar) would have on half-cell reactions. Normally, I'd use the Nernst Equation, but under immense pressures the value "R" is no longer ideal (pun intentional). The electrical pressure (voltage) goes up because (I would assume because) the number of joules goes up, since the pressure is increased there's more energy at a given temperature (but I have no idea how much)... plus no gas is ideal, especially at high pressures. I'm designing an "amateur" experiment doing high pressure electrolysis. If anyone knows of any papers on this subject, or can point me in a new direction- that would be very kind of you. I've already asked a few professors (one chemistry, two physics) and we got no where; I looked on google scholar and I can't find anything useful. Approximations won't be very helpful, experimental data would be most helpful (since I hear overpotentials must be determined experimentally). It'd be neat to compare the different electrode efficiencies, but I'm mostly interested in the relationship between pressure and voltage for electrolysis (I hope its linear).
