question 47

Multiple Choice

Calculate E°_cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous.

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) Spontaneous, but none of the above values of E°_cell is correct.
