QUESTION 13 The rate In an aqueous solution at 223.15 K, the diffusion coefficient of Hemoglobin (r-35 À ) is 76x1024cm2 and for 02 (-20) )is 1.2x10-12 cm. constant for binding 02 to Hemoglobin is 4.0x10? Is this a diffusion-controlled reaction? Find neceway parameter and explain your opinion. E. BI TTT T Paragraph - Arial (12pt) *DQQETETT. O S.O .S. T. -- M

Answer 1

Given Diffusion - Diffusion coeloficient far hemoglobin (80) = 35 A = 3.5x15 cm Diffusion coefficient for O₂ (22) = 2 A =0.2 x 10 cm Diffusion coefficient for hemoglobin (Di) = 9.68 10 cu " » par Oz (O2) = 1.2 X 10 12 cm² st find rate constant noglobin (Di) = 9.6x10th antgal 10 A = 6.02 x - CNA = 6:02 x 1023) Kal=45XNA (ritre) CDI + Dz) mart = 4 x3•14 x 6.02% 1023 (3.5x10 ton + 0.2 x 10cm) (7.6X10 + 1.28106 mole mole aos me = 3.56 x 106 cm² ,-1 molt = 3.56 x 10 misl molarity - Tooo (m3 Here than so this Rate diffusion reaction is constant 3.56 x 103 misal is smalles limited eate constant 4.7x10 m 87 diffusion limited.
