Consider the following electrode potentials:
Mg2+ + 2e–→ Mg E° = –2.37 V
V2+ + 2e–→ V E° = –1.19 V
Cu2+ + e–→ Cu+ E° = 0.16 V
Which one of the reactions below will proceed spontaneously from left to right?
◦
Mg2+ + V → V2+ + Mg◦
Mg2+ + 2Cu+→ 2Cu2+ + Mg◦
V2+ + 2Cu+→ V + 2Cu2+
◦
Mg + 2Cu2+→ Mg2+ + 2Cu+
◦
None of these are correct.
