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. I₂(s) + 2e^-
2I^-(aq) E° = 0.53 V
Cr³⁺(aq) + 3e^-
Cr(s) E° = -0.74 V
Overall reaction:
2Cr(s) + 3I₂(s) → 2Cr³⁺(aq) + (aq) + 6I^-(aq)

A) E°_cell = -1.27 V, spontaneous
B) E° _cell = -1.27 V, nonspontaneous
C) E° _cell = 1.27 V, spontaneous
D) E° _cell = 1.27 V, nonspontaneous
E) E° _cell = 1.54 V, spontaneous
