Calculate E°_cell and Indicate Whether the Overall Reaction Shown Is

question 62

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
