What Is E°_cell for the Following Reaction,and Is It Spontaneous

question 55

Multiple Choice

What is E°_cell for the following reaction,and is it spontaneous or nonspontaneous under standard-state conditions? 2Fe³⁺(aq) + 2H₂O(l) → H₂O₂(aq) + 2H⁺(aq) + 2Fe²⁺(aq)
Given:
H₂O₂(aq) + 2H⁺(aq) + 2e^-
2H₂O(l) E° = 1.77V
Fe³⁺(aq) + e^- Fe²⁺(aq) E° = 0.77V

• 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
