Explain reaction shown is spontaneous or nonspontaneous

Reference no: EM13246777

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)
