How to Calculate Eº for 2Cu⁺(aq) → Cu²⁺(aq) + Cu(s)?

[An1MuS]

Given E^{0}=0,52V for

Cu^{+}(aq) + e^{-} --> Cu(s)

Calculate E^{0} for the following reaction at 25ºC, 1atm.

2Cu^{+}(aq) --> Cu^{2+}(aq) + Cu(s)

Any ideas?

Is that all the data you're given? Don't you need the E^{0} for Cu+ => Cu2+?

While doing these exercises we can check the standart potential reduction table.

E0 for Cu+ => Cu2+ + 1e- is -0,15V

What would you do then?
