Given that E^o = 0.52 V for the reduction of Cu+(aq) + e - (yields) Cu(s)

Question

Calculate E^o, (delta)G^o and K for the following reaction at 25°C.
2Cu2+(aq) (yields) Cu2+(aq) + Cu(s)

Answer 1

I think you have made a typo. It makes the difference between a half reaction and a complete reaction. Note that the charges don't balance. I see +4 on the left and +2 on the right.
I THINK what you meant to type is
2Cu^+(aq) ==> Cu^2+ + Cu(s)

Answer 2

That's actually word for word from the problem. That's why I've been having so much difficulty with it. The answers were given as 0.37 V, -36 kJ, and k = 2x10^6. I just want to understand how it's possible.
