Hemoglobin (hb) can react with both o₂ and co at 37 °c. the reaction below shows how co can displace o₂ from hemoglobin with a k = 2.0 x 10² :
hbo₂(aq) + co(g) < ===> hbco(aq) + o₂(g)
if the ratio [hbco]/[hbo₂] comes close to 1, death will happen. what partial pressure of co is fatal? assume the partial pressure of o₂ is 0.20 atm (since air is 20% o₂).
a) 1000 atm
b) 0.2atm
c) 200 atm
d) 4 x 10⁻⁴ atm
e)1 x 10⁻³ atm
