Question 66

Multiple Choice

Calculate E°_cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous.
I₂(s) + 2e^- $Calculate E°cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. I2(s) + 2e- 2I-(aq) ;E°= 0.53 V Cr3+(aq) + 3e- Cr(s) ;E°= -0.74 V Overall reaction: 2Cr(s) + 3I2(s) \to 2Cr3+(aq) + (aq) + 6I-(aq) A) E°cell = -1.27 V,spontaneous B) E°cell = -1.27 V,nonspontaneous C) E°cell = 1.27 V,spontaneous D) E°cell = 1.27 V,nonspontaneous E) E°cell = 1.54 V,spontaneous$
2I^-(aq) ;E°= 0.53 V
Cr³⁺(aq) + 3e^- $Calculate E°cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. I2(s) + 2e- 2I-(aq) ;E°= 0.53 V Cr3+(aq) + 3e- Cr(s) ;E°= -0.74 V Overall reaction: 2Cr(s) + 3I2(s) \to 2Cr3+(aq) + (aq) + 6I-(aq) A) E°cell = -1.27 V,spontaneous B) E°cell = -1.27 V,nonspontaneous C) E°cell = 1.27 V,spontaneous D) E°cell = 1.27 V,nonspontaneous E) E°cell = 1.54 V,spontaneous$
Cr(s) ;E°= -0.74 V
Overall reaction:
2Cr(s) + 3I₂(s) $\to$ 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
