Just for clarification from Friday's lecture, why does the E of a reduction/oxidation reaction not change whenever you alter a reaction by multiplying the coefficients? Thanks in advance!

E does not change because if you look at the equation it is evident that delta G doubles when the stoichometric coefficients are doubled. However, the change in the number of moles, or delta n, also doubles. Since both delta G and delta n doubles, it does not affect delta E in the equation, meaning the cell potential does not change.
