The \[{{E}^{\bigcirc -}}_{C{{U}^{2+}}(aq)/Cu(s)}\] is +\[+0.34\text{ }V\]                                                                                                This is represented as below:  The positive \[{{E}^{\bigcirc -}}\] value is due to:                                                                                          

(I) Due to low sum of \[(I{{E}_{1}}+I{{E}_{2}}+{{\Delta }_{sub}}{{H}^{\bigcirc -}})\] values and more \[-ve{{\Delta }_{hyd}}{{H}^{\bigcirc -}}\] value.

(II) Due to high sum of \[(I{{E}_{1}}+I{{E}_{2}}+{{\Delta }_{sub}}{{H}^{\bigcirc -}})\] values and less \[-ve{{\Delta }_{hyd}}{{H}^{\bigcirc -}}\] value.

(III) Reduction of \[C{{u}^{+2}}_{(aq)}\] to \[Cu(s)\] is favourable.

(IV) Oxidation of \[Cu(s)\] to \[C{{u}^{+2}}_{(aq)}\]is favourable.
