Relation Between Emf G Kc Ph

What is the correct order of ionic mobility of the following ions in an aqueous solution?

Given:
(i) ${\mathrm{Cu}}^{2+}+2{\mathrm{e}}^{-}\to \mathrm{Cu}$ E^o = 0.337 V
(ii) ${\mathrm{Cu}}^{2+}+{\mathrm{e}}^{-}\to {\mathrm{Cu}}^{+}$ E^o = 0.153 V
Electrode potential, E^o for the reaction,
${\mathrm{Cu}}^{+}+{\mathrm{e}}^{-}\to \mathrm{Cu}$, will be:

1. 0.52 V

2. 0.90 V

3. 0.30 V

4. 0.38 V

A hydrogen gas electrode is made by dipping platinum wire in a solution of HCl of pH = 10 and by passing hydrogen gas around the platinum wire at one atm pressure. The oxidation potential of the electrode would be:
