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
