Question

The Eθ(M²⁺/M) value for copper is positive (+0.34V). What is possibly the reason for this?
(Hint: consider its high Δ_aH^θ and low Δ_hydH^θ)

Answer 1

The E^θ(M²⁺/M) value of a metal depends on the energy changes involved in the following:
1. Sublimation: The energy required for converting one mole of an atom from the solid
state to the gaseous state.
