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
