anything but irrelevent.this shit is going down.this is shit you can measure in your lab like i said namsayn but i cnt exactly prove that from a video-tape.your gona have to trust the nernst equation and also what wikipedia said bowt entropy preferences under title 'concentration cell'

its gota be perfect so we want the best text-cites namsayn @sarkeizen.chill for a while..brb
According to you it's in every textbook everywhere in a form that leaves no room for question....

I think you were kind of lying about that.

How hard can this be?  You said it's in every electrochemistry textbook but you can't just go and open one.  Find the thing you are talking about.  Write down the page number and the title of the book.  Then type those things here.

Seriously.  Are you crippled in some way that you haven't discussed?

I think that this statement neatly embodies a great deal of the misconception:

Quote
so lets go with the textbook flow your highness sir-sarkeizen: the corrosion textbooks say that the oxygen concentration potential will keep rusting the point on the iron,steadily,continuously,over days,months,years,tens of years.this sound like a persistent potential to you? Sounds like a persistent potential to me.with total complete gaseous communion.(try a rusting experiment sometime).thus we safely conclude the standardised equi-pressure oxygen gas concentration cell to posess a permanently stable nernstian rest potential,in breach of kelvin laws.   

The statement ignores that absent a steady supply of fresh oxygen, the oxygen reduced into oxide depletes just as the supply of unoxidized iron declines.  Whether the battery runs out of oxygen or iron first, it winds down.  Profitis' concept for a perpetual battery seems to depend on the availability of an infinite supply of feed stock reactants.

totaly incorrect @mark E.i said differential aeration corrosion relies on a constant oxygen concentration gradient potential to work,with free communion of gas,in gross contrast to your earlier statement about oxygen concentration potentials with communion.the galvanic action of the iron having nothing to do with the creation of the aeration differiential potential,in fact only emphasising my point of a stable nernst o2 potential at rest regardless of gas communion. You also failed to defend yourself by explaining why 2 totaly seperate pieces platinum sitting at different depths in electrolyte under one atmosphere pressure will not measure equal potential in seperate boxes against a reference electrode but will (according to you) register the same potential under a joined box under one atmosphere.

Profitis it you won't be held to your own statements, then you define yourself, and not well at all.

In the meantime, it has been four days already and there is no sign that you will be coming up with that reference that you promised Feb. 14:

im going to have to hunt for one mark E. But dont you think that the o2 potential on the anode is diluted by the larger surface area of submerged electrode surface and the potential more concentrated on the cathode with less area for charge distribution?

lol mark E maybe your on my side here.just integrate diffusion co-efficients of oxygen species into the nernst equation from the gorgeous BUTLER-VOLMER classic equation (see wikipedia) and we get for an o2 electrode that deviates from standard reversability due to kinetics : O2 + 4H+ + 4e- >kf/kb< 2H2O where kf and kb are the rate constants of forward and backward reactions respectively. Integrated thus: E for oxygen electrode = RT/nFe ln kf/kb + RT/nFe ln c[H+] c[H2O]/c[O2]  where concentration of water is taken as unity.thus we see how kinetic diffusion constraints directly affect the REST potential of an gaseous electrode,the difference in diffusion constraints between 2 same such electrodes giving rise to a REST potential difference.

Equations are all fine and well when applied to the appropriate circumstances.  Time keeps ticking by and that cite your were going to locate seems no closer.  In the meantime, in that quote of yours I cited you relied upon an infinite supply of reagents to keep the reaction from stopping when the feed stock exhausts.  Everything you have talked about so far, in the absence of external energy, keeps driving towards equilibrium not away from equilibrium.

where did i say theres a drive away from equilibrium @mark E? No i agree with you,it goes straight to equilibrium,one of two equilibriums,an electrochemical one OR a gaseous diffusion one.you just choose which one at a flick of a switch.you cannot just dismiss the butler-volmer equation as it applies directly here proving you wrong about zero rest potential,and proving you right about a kelvin breach..

Since I haven't ever uttered the words on this forum:  "zero rest potential" how can I be either right or wrong about such a thing?

Let me know if you ever find that reference you promised.  I'll give it about three more days before I conclude that you can't find one.

youre saying your open to the butler-volmer equation grossly enforcing a open-circuit rest potential in my diagrammed wikipedia oxygen concentration cell with total gas communion @mark E?

Getting your claim refuted that I said something I never did doesn't earn you new chances.

Let me know if you ever come up with that reference you promised.

lol @mark E! So you are open to the butler-volmer equation grossly disturbingly nuisancely thrusting a nicey stabley rest potential on the wikipedia o2 cell :D.halleluya,its going to rain money tonight! :D

You should be more concerned about getting over your disability which prevents you from looking something up in a book and posting it and a specific reference to it online.
