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.30 Cu²⁺⁽^aq) + 22 Al(s) → 30 Cu(s) + 22 Al³⁺(aq)

Question

Quizplus · Accepted Answer

The standard cell potential, E°, depends only on the difference in the standard reduction potentials of the two half-cells involved in the reaction. In both reactions, the reduction half-reaction for Cu2+ to Cu has the same standard reduction potential, and the oxidation half-reaction for Al to Al3+ has the same standard oxidation potential. Therefore, the standard cell potentials for the two reactions should be the same.
