Hi!
So, here n refers to the number of electrons that are being transferred...
Let us take the equation Cu^2+ + Zn ---> Zn^2+ + Cu for example..
Split the reaction into the two half reactions...
Cu^2+ + 2e ----> Cu and Zn -----> Zn^2+ + 2e
Clearly, n here is 2.
When the number of electrons in both the half reactions are different, multiply both equations by a suitable number so that n becomes equal in both and use that value of n in the equation...
Hope it helps :D
