Given, standard electrode potentials, Fe2+ + 2e- →Fe, E° = -0...
Calculation of Standard Electrode Potential for Fe3+ + e- → Fe2+
1. Given Data:
- E° for Fe2+ + 2e- → Fe = -0.440V
- E° for Fe3+ + 3e- → Fe = -0.036V
2. Using Nernst Equation:
- E°cell = E°cathode - E°anode
- E°cell = E°(Fe2+ → Fe) - E°(Fe3+ → Fe)
- E°cell = -0.440V - (-0.036V)
- E°cell = -0.440V + 0.036V
- E°cell = -0.404V
3. Reversing the Reaction:
- Since the given reaction is Fe3+ + e- → Fe2+, we need to reverse it to get Fe2+ + 2e- → Fe
- Reversing the reaction changes the sign of E°, so E° = 0.404V
Therefore, the standard electrode potential (E°) for Fe3+ + e- → Fe2+ is +0.404V.
