Question
Calculate the equilibrium constant, K, for the reaction shown at 25 °C.
Fe+(aq)+B(s) + 6 H, O(1) → Fe(s) + H,BO,(s) + 3 H,O*(aq)
The balanced reduction half-reactions for the equation and their respective standard reduction potential values (E") are
Fe3+ (aq) + 3 e- → Fe(s)
H,BO, (s) + 3 H,0*(aq) + 3 e- – B(s) + 6 H, O(1)
E' = -0.04 V
E' = -0.8698 V
K =
