The electrode potentials for Cu2+ + e- -------- Cu+(aq) and Cu+(aq) + e- ------- Cu(s) are +0.15V and +0.50V respectively. The value of ECu2+/Cu will be?

1- 0.15V 2- 0.5V

3-0.325V 4- 0.650V

Cu2+  +   e  ...............    Cu+       E= +0.15 V
Cu+ +   e     ...............    Cu       E= +0.50 V

Ecell  =  Ecathode -  Eanode
