Ans. X DAB = 0.897 x 10-m-/s (282.9 K), DAB = 1.396 x 10-9 m/s (288 K) 18.2-4. Estimation of Diffusivity of Methanol in H20. The diffusivity of dilute methanol in water has been determined experimentally to be 1.26 x 10-m?/s at 288 K. (a) Estimate the diffusivity at 293 K using the Wilke-Chang equation. (b) Estimate the diffusivity at 293 K by correcting the experimental value at 288 K to 293 K. (Hint: Do this by using the relationship DAB a TIMB.) 18,2-5. Estiu 1
