### Problem 6N.1 part b

Both the half reactions for In3+/In2+ and U3+/U4+ use only one electron and it balances out correctly. So, why does the solution manual uses 2e- for n?

I believe the solutions manual is wrong.

You can find n by balancing the half reactions in a given redox reaction. Because the amount of electrons transferred in oxidation equals the amount transferred in reduction, you can find a single value for n, the number of moles of electrons transferred in total.

yes, if both half reactions only show 1 mole of electrons being transferred then n=1 thus the solution manual is wrong

Yeah I noticed the same error, I think it's just a mistake.
