What is the relationship between the standard cell potentials,E°,for the following two galvanic cell reactions?
I.3 Cu²⁺⁽^aq) + 2 Al(s) → 3 Cu(s) + 2 Al³⁺(aq)
II.6 Cu²⁺⁽^aq) + 4 Al(s) → 6 Cu(s) + 4 Al³⁺(aq)

Question

Quizplus · Accepted Answer

The standard cell potential (E°) of a galvanic cell reaction depends on the difference in the standard electrode potentials (E°) of the two half cells involved in the reaction. In this case, both reactions involve the same half reactions of Cu2+ + 2e- → Cu and Al3+ + 3e- → Al. Therefore, the standard electrode potentials are the same for both reactions, and the difference in potential (E°) between the two half cells is the same. As a result, the standard cell potentials (E°) for both reactions are the same, and the answer is A.
