Explain why cell potentials are not multiplied by the coefficients in the balanced redox equation. (Use the relationship between delta G and cell potential to do this.)

i know cell potential is an intensive property but i don't know how to explain why you don't multiply the the cell potentials by the coeffients using delta G.

Any relationship you know of between them? Equation?

[demonat0r]

well i know that

delta G = -nF(cell potential)

where n is the number of moles of electrons exchanged in the redox reaction and F is the constant Faraday which is 96,485 coulombs of charge per mole of electrons.

i don't think the equation helps to explain why you can't multiply the cell potential by the coefficients of the balanced equation though.

Well, that's what your question wants. I know you could simply argued that cell potential is an intensive property and that is it doesn't depend on the amount of material so stoichiometric ratio doesn't affect the cell potential at all.

hm...
does anyone know how to use this equation to answer the question?

please help me asap.

Perhaps from the equation, delta G is directly proportional to cell potential, as you know a positive cell potential has a negative gibbs free energy change, and vice versa. This is always true. So cell potential is proportional to gibbs free energy change and not proportional to stoichiometric coefficient. I would think the intesive property would be good enough but that's not what your question wants though. My two cents' worth

haha thanks for trying it.
i tried googling for info but i couldn't find anything. the answer to this question isn't in my textbook either.
if anyone knows the answer plz plz help me.
