### Standard Reduction Potential

How come the standard reduction potentials stay the same when half reactions are balanced?

I think because standard reduction potential is an intensive property so the amount that the reaction occurs doesn't matter.

From a mathematical standpoint, if you take a look at the equation deltaG = -nFE, and rearrange it into E = -deltaG/nF, you will see that if we multiply the chemical reaction by a factor, both deltaG and n change by that factor, so the net result is no change to the value of E.

Even when you multiply the half reactions by a factor in order to balance the number of electrons, the overall change of E does not change, while the value of delta G does.
