Question 34

Multiple Choice

Calculate E°_cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous.
$Calculate E°cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. Overall reaction: 4Al(s) + 3O2(g) + 12H+(aq) \to 4Al3+(aq) + 6H2O(l) A) E°cell = -2.891 V, nonspontaneous B) E°cell = -2.891 V, spontaneous C) E°cell = 2.891 V, nonspontaneous D) E°cell = 2.891 V, spontaneous E) Spontaneous, but none of the above values of E°cell is correct.$
Overall reaction: 4Al(s) + 3O₂(g) + 12H⁺(aq) $\to$ 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.
