Hello! The best way I would approach this problem is to first determine which electrode is your cathode and which is your anode. You can do this by altering the neg/pos sign of the individual standard potentials to see which combination gives you the most positive overall Ecell using cathode-anode. Once you’ve done that, it can also help to visualize the reaction by writing out the cell notation or the full rxn to see how many e- are being transferred. Additionally, you want to note that the Gibbs free energy of the cell reaction is = the maximum amount of nonexpansion work the cell can do. Therefore, you can go ahead and plug in your numbers to find deltaG. Hope this helped!
