Carbon monoxide and the cyanide ion are both toxic because they bind more strongly than oxygen to the iron in hemoglobin (Hb). Hb + O_2 HbO_2 K = 2 Times 10^12 Hb + CO HbCO K= 1 Times 10^14 Calculate the equilibrium constant value for the reaction: HbO_2 + CO HbCO + O_2 Express your answer using one significant figure. Does the equilibrium favor reactants or products? reactants products
