Question

which transition metal of 3d series has positive Eo
(M2+/M) value and why??

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!
