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

Multiple Choice

Calculate E°_cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. H₂O₂(aq) + 2H⁺(aq) + 2e⁻ ⇄ 2H₂O(l) E° = 1.77 V
Fe³⁺ (aq) + e⁻ ⇄ Fe²⁺(aq) E° = 0.77 V
Overall reaction:
2Fe³⁺(aq) + 2H₂O(l) → H₂O₂(aq) + 2H⁺(aq) + 2Fe²⁺(aq)

A) E° _cell = −1.00 V, nonspontaneous
B) E° _cell = −1.00 V, spontaneous
C) E° _cell = 1.00 V, nonspontaneous
D) E° _cell = 1.00 V, spontaneous
E) E° _cell = −0.23 V, nonspontaneous
