Last updated: 7/6/2022

Carbon monoxide (CO) is toxic because it binds more strongly to the iron in hemoglobin (Hb) than does oxygen (O₂), as indicated by these approximate standard free-energy changes in blood: reaction A: Hb + 0₂ Estimate the equilibrium constant K at 298 K for the equilibrium K= Express your answer numerically using one significant figure. reaction B: Hb+CO HbCO, AG = -80 kJ/mol →→HbO₂, ? AG=-70 kJ/mol HbO, +CO , HbCO+O2
