Question
Carbon monoxide is toxic because it bonds much more strongly to the iron in hemoglobin (Hgb) than does O2. Consider the following reactions and approximate standard free energy changes:
Hgb + O2 HgbO2
AG° = -70 kJ
Hgb + CO → HgbCO
AG = -80 kJ
Using these data, estimate the equilibrium constant value at 25°C for the following reaction:
HgbO, + CO = HgbCO + O2
[R=8.314 J/(K mol); 1 kJ = 1000 J]
K =
