The standard reduction potentials of Cu2+/Cu and Cu2+/Cu+ are 0.337Vand 0.153V respectively. The standard electrode potential of Cu+/Cu half cell is:0.184V0.827V0.521V0.490V

Cu2++2e→Cu;Eo=0.337V∴−ΔGo=−2×0.337×FCu+→Cu2++e−;Eo=0.153V∴−ΔGo=0.153×1×F−−− (by substracting)----------------------------------------------------------------------------------------------------Cu++e→Cu,−ΔGo=−0.521F

The standard reduction potentials of $C u^{2 +} / C u$ and $C u^{2 +} / C u^{+}$ are $0.337 V$ and $0.153 V$ respectively.

The standard electrode potential of $C u^{+} / C u$ half cell is:

$0.184 V$
$0.827 V$
$0.521 V$
$0.490 V$
