The protein hemoglobin (hb) transports o2 in mammalian blood. each hb can bind 4o2 molecules. the equilibrium constant for the o2-binding reaction is higher in fetal hemoglobin than in adult hemoglobin. in discussing protein oxygen-binding capacity, biochemists use a measure called the p50 value, defined as the partial pressure of oxygen at which 50% of the protein is saturated. fetal hemoglobin has a p50 value of 19 torr, and adult hemoglobin has a p50 value of 26.8 torr. use these data to estimate how much larger kc is for the aqueous reaction 4o2(g)+hb(aq)→[hb(o2)4(aq)].

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

a is the correct answer

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
