Carbon monoxide is toxic because it binds more strongly to
the iron in hemoglobin (Hb) than does O, as indicated by
these approximate standard free-energy changes in blood:
Hb + 0, → HbO, AG° = -70 kJ
Hb + CO
HBCO
HЬСО
AG° = -80 kJ
Using these data, estimate the equilibrium constant at 298
K for the equilibrium
HbO, + CO =
HÃœCO + O2
