Enterobactin (Ent) is a special ligand secreted by some bacteria to sequester Fe from the environment (Fe is an essential nutrient for almost all living species, see Section 26.6). The equilibrium constant for formation of [Fe(III)(Ent)] (10⁵² mol⁻¹ dm³) is at least forty orders of magnitude higher than the equilibrium constant for the corresponding Fe(II) complex. Determine the feasibility of releasing Fe from [Fe(III)(Ent)] by its reduction to Fe(II) under conditions of neutral pH, noting that the strongest reducing agent normally available to bacteria is H₂.
