Could someone please explain why when you multiply a half reaction, the E does not change? I'm just confused why entropy and enthalpy change when the reaction is flipped or multiplied bye E does not. I know that there is a difference because S and H are thermo and E is electric, but I do not get why the value is not affected by the coefficients changing.
It's because entropy and enthalpy are EXtensive properties. The more wood you burn, the more heat it will give off (enthalpy). The more of something you have, the more disordered it can be (entropy). On the other hand, E is an INtensive property. By definition, it doesn't matter how much of something you have; E will remain the same.
