Question

Use the following half-cell reactions to write three spontaneous reactions. Calculate E°cell for each reaction and then rank the strengths of the oxidizing and reducing agents.

  1. Al3+ (aq) + 3e- Al (s) E° = -1.66 V
  2. N2O4 (g) + 2e- 2NO2— (aq) E° = 0.867 V
  3. SO42- (aq) + H2O (l) + 2e- SO32- (aq) + 2OH- (aq) E° = 0.93 V
