Question:

Will reaction (23.25) still be spontaneous in the forward direction in a solution containing equal concentrations of Fe²⁺ and Fe³⁺, a pH of 3.25, and under an O₂(g) partial pressure of 0.20 atm?

Reaction (23.25)

4 Fe+ (aq) + O(g) + 4H+ (aq) 3+ 4 Fe+ (aq) + 2 HO(1) Ecell = 0.44 V (23.25)
