Calculate E°_cell and Indicate Whether the Overall Reaction Shown Is

question 84

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.
