### 14.9

Calculate the standard Gibbs free energy for the following cell reactions:
a) 2Ce+4 + 3I- ----> 2Ce+3 + I3-, Ecell=+1.08V

I know we used deltaG= -nFE but how do we find n? I thought we need to be given the number of electrons in the reaction.

Write out the half-reactions of the given reaction - the n will correspond to the number of electrons being transferred in the balanced half-reactions.
