Calculate E° _Cell and Indicate Whether the Overall Reaction Shown

question 64

Multiple Choice

Calculate E° _cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. O₂(g) + 4H⁺(aq) + 4e^-
2H₂O(l) E° = 1.229 V
Al³⁺(aq) + 3e^-
Al(s) E° = -1.662 V
Overall reaction:
4Al(s) + 3O₂(g) + 12H⁺(aq) → 4Al³⁺(aq) + 6H₂O(l)

• A) E° _cell = -2.891 V, nonspontaneous
• B) E° _cell = -2.891 V, spontaneous
• C) E° _cell = 2.891 V, nonspontaneous
• D) E° _cell = 2.891 V, spontaneous
• E) None of these choices are correct.
