### G=-nFE

When we use deltaG=-nFE, how do we know what n to use?

In this equation, n=the number of electrons transferred in the redox reaction.

After balancing the half reactions at the anode and cathode, and multiplying by whatever number to make the number of electrons the same in the cathode and anode half reactions, you would use the number of electrons in either the anode or cathode half reaction as n (it should be the same number for either).

n is the number of moles of electrons transferred in the reaction, and I find it easiest to use the coefficient from the balanced half reaction

### Re: G=-nFE

n is the number of electrons transferred. Once you balance the half reactions, the number of electrons transferred are equal to each other because they cancel out when you combine the two half reactions to create the full reaction.

We use this equation when calculating delta G in standard and nonstandard conditions.
In order to calculate n, you must write the reduction and oxidation half reactions, balance them, and then observe the number of electrons transferred.
