Question

E(m2+/m) value for copper is positive(+0.34v) what is possibly the reason for this

Answer 1

Copper has high atomization delta aH°and low hydration energy delta hyd. H°. Due to which the E°value is postive

Answer 2

The possible reason for the E(m2+/m) value for copper is positive(+0.34v)  is given below.

Explanation:

E⁰ of  Copper (Cu) is positive due to the high ionisation or high atomisation energy and low hydration energy associated with it.

Also,

  Atomization energy is the energy required to remove electrons from one mole of the atom. for copper, it requires electrons to complete its octet.

Hydration energy is the energy which is used in the hydration of one mole of ion.
