What is the standard electrode potential of carbon?
It doesn't have one! Check this: if you hook up a carbon electrode to any metal (that isn't as cathodic as carbon, such as gold) then you'll come up with a NEGATIVE potential. Read More »

How is the standard electrode potential..?
the polarity depends whether the power is supplied externally or the power is being generated. for electrolysis where the power supplied externally, the cathode is negative the anode is positive. example cu plating the 2 electrodes plug int... Read More »

This is the E generated when all gases are at 1 bar and all solutes at a concentration of 1M, so the activity of all chemicals present equals 1. The environmental pressure is equal to 1 bar as well. Although there's no standard temperature,...

Because we can only measure relative potentials, so we need to designate some point as zero. Hydrogen is a pretty good choice, since that way we can tell whether a given substance will react with acids to liberate hydrogen or not just based...

crudly writing a rendition of it as Ehalfcell = Ezero - [RT/nF] ln Q You are correct in that by fixing Q at 1, that term becomes zero and such does the whole subtracted term. But Ezero is NOT A CONSTANT Ezero changes with respect to tempera...
