Solution

Dear Student,
Copper is the metal of 3d series which has positive value of E_(M²⁺/M). The electrode potential values depend upon the Enthalpy of atomization , ionization enthalpy and heat of hydration.
Copper has a high heat of atomization and low heats of hydration and more energy is required to Cu to Cu²⁺ and therefore E⁰ value for copper is positive, E⁰_(Cu²⁺/Cu)=+0.34V
Regards!
