Explanation Given Partial pressure of oxygen in a fetus for oxygen binding reaction is 19 torr . Partial pressure of oxygen in an adult for oxygen binding reaction is 26.8 torr . The given oxygen binding reaction is, 4 O 2 ( g ) + Hb ( a q ) ⇌ [ Hb ( O 2 ) 4 ( a q ) ] Since the reaction takes place in human body, the temperature of the reaction is 37 °C . The conversion of degree Celsius ( ° C ) into Kelvin ( K ) is done as, T ( K ) = T ( °C ) + 273.15 Hence, the conversion of 37 °C into Kelvin ( K ) is, T ( K ) = 37 ° C + 273.15 = 310.15 K Conversion of 1 torr into atm is done as, 1 torr = 0 .0013 atm Therefore, conversion of 19 torr into atm is, 19 torr = 19 × 0.0013 atm = 0.0247 atm Therefore, conversion of 26.8 torr into atm is, 26.8 torr = 26 .8 × 0 .0013 atm = 0 .0348 atm Concentration of O 2 in a fetus is calculated from the formula, [ O 2 ] 1 = P 1 R T Where, [ O 2 ] 1 is the concentration of O 2 in a fetus. P 1 is the partial pressure of O 2 in a fetus. R is the gas constant ( 0.08206 atm ⋅ L/mol ⋅ K ) . T is the normal temperature of human body. Substitute the values of P 1 , R and T in the above formula. [ O 2 ] 1 = 0.0247 atm 0.08206 atm ⋅ L/mol ⋅ K × 310.15 K = 9.705 × 10 − 4 mol/L = 9.705 × 10 − 4 M The equilibrium constant of the oxygen binding reaction in a fetus is calculated by the formula, K c 1 = [ Hb ( O 2 ) 4 ] [ Hb ] [ O 2 ] 1 4 Where, K c 1 is the equilibrium constant for oxygen binding reaction in a fetus. [ Hb ( O 2 ) 4 ] is the concentration of Hb ( O 2 ) 4 . [ Hb ] is the concentration of hemoglobin. Substitute the value of [ O 2 ] 1 in the above formula. K c 1 = [ Hb ( O 2 ) 4 ] [ Hb ] ( 9
