The binding of oxygen by hemoglobin (Hb), giving oxyhemoglobin (HbO₂), is partially regulated by the concentration of H₃O⁺ and dissolved CO₂ in the blood. Although the equilibrium is complicated, it can be summarized as 

HbO₂(aq) + H₃ O⁺(aq) + CO₂(g) ⇌ CO₂ −Hb−H⁺ + O₂(g) + H₂ O(l)

(a) Write the equilibrium constant expression for this reaction.
