1. Carbon monoxide poisoning can happen because carbon monoxide has a higher affinity for hemoglobin than oxygen does. This can be seen by comparing the equilibrium constants for the two reactions Hb(a)+02()Hb02(aq) Hb(a)C(e) HbCO(aq) K 1.9x1012 K 1.1x1014 where Hb is hemoglobin. The actual reactions are more complicated since each hemoglobin can accept up to four oxygen molecules, but we will simplify it for this problem A concentration of about 12,500 parts per million of CO is considered highly lethal....
