I know that in the G=-nFe equation, n is the number of electrons transferred. Does that mean the electrons transferred from 1 compound to another? I'm confused because in a lot of equations, everything rearranges from one side to the other...
n indicates the number of electrons that are involved in the transfer between the oxidizing agent and reducing agent. When you have your two half-reactions for OX and RED, you have to balance your electrons to make sure your electron transfer is balanced out. The balanced value of electrons is what you use for the n value. This forum's https://chemistry.stackexchange.com/questions/5122/how-is-it-determined-how-many-electrons-are-transferred-in-redox-reactions top answer does a good job explaining this!
n is the number of electrons transferred in the redox equation. When you do your reduction half reaction there is a certain amount of electrons transferred and same case for the oxidation half reaction. You then have to multiply the equations to balance the electrons. when they match and cancel that number is n
