molecule). Suppose that the chemical potential of O, in the air in the
lungs at a body temperature of 310 K is u(O2) = -.6 eV. The energy of
a hemoglobin adsorption site is 0 when it is empty, -0.7 eV when occupied
by an O2 molecule, and -0.85 eV when it is occupied by a CO molecule.
(a) First, consider the case of when there is no CO present in the air. What
is the Gibbs sum for the hemoglobin site, and what is the probability
that a hemoglobin site in the lungs is occupied by an O2 molecule?
(b) Now suppose there is CO present in the air at an abundance of 1/100
of that of O2. Estimate the value of the chemical potential u' for CO
in the air at 310 K (you can assume that the masses of CO and O2
molecules are approximately equal).
(c) What is the Gibbs sum and the probability that a hemoglobin is occu-
pied by an O2 molecule?
