What Is E°cell for the Following Reaction, and Is It

Question 27

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: What is E°<sub>cell</sub> for the following reaction, and is it spontaneous or nonspontaneous under standard-state conditions? 2Fe<sup>3+</sup>(aq) + 2H<sub>2</sub>O(l) → H<sub>2</sub>O<sub>2</sub>(aq) + 2H<sup>+</sup>(aq) + 2Fe<sup>2+</sup>(aq) Given: A) E°<sub>cell</sub> = -1.00 V, nonspontaneous B) E°<sub>cell</sub> = -1.00 V, spontaneous C) E°<sub>cell</sub> = 1.00 V, nonspontaneous D) E°<sub>cell</sub> = 1.00 V, spontaneous E) E°<sub>cell</sub> = -0.23 V, nonspontaneous


A) E°cell = -1.00 V, nonspontaneous
