Standard Potential

Postby Madison Hurst » Tue Feb 26, 2019 1:18 am

if the coefficients are proportional but different in the same 2 reactions, do you need to multiply E by the molar proportion or does it stay the same?

Eo is an intensive property, so you never multiply it by the molar proportions of reactants and products.

Eo is an intensive property (the voltage difference is the same and does not depend on how many times the reaction occurs). It stays the same when the half reaction is balanced. However, when one of the half reactions must be reversed, the sign of Eo changes.
