Calculate the equilibrium constant, K, for the following reaction at 25 °C.
Fe3+(aq) + B(s) + 6H2O (l) -→ Fe(s) + H3BO3(s) + 3H3O+(aq)
The balanced reduction half-reactions for the above equation and their respective standard reduction potential values (E°) are as follows:
Fe3+(aq) + 3e- → Fe(s) E= -0.04 V
H3BO3(s) + 3H3O+(aq) + 3e- → B(s) + 6H2O(l) E= -.8698 V
K = ?
