Estimate the liquid diffusivity of phenol in ethanol at 25C and infinite solution. Hint: Use the Wilke-Chang equation. Dynamic viscosity for the solvent is 1.2 mPa's. OH HH I 1 H-C-C-0-H HH - Experimental DAB = 8 x 10 m/s a) Determine the diffusivity of phenol in ethanol at 25C. [4 Marks) b) Calculate the percentage error. [2 marks] c) Comment on the percentage error and compare your results. [2 marks] d) State four assumptions for this case, [2 marks]
