The diffusivity of carbon dioxide in liquid toluene was curve-fitted to the measured data by the following expression: DAB=2.96103e1224.5/Tincm2/s where T is in kelvins. Independent measurements of the viscosity of toluene as a function of temperature can be curve-fit by the expression =0.0152e1072/TincP (a) Use the Wilke-Chang equation to predict DAB for temperatures of 300 and 350K. (b) Compare the diffusivities predicted by the Wilke-Chang equation to the empirical/curve-fitted equation at temperatures of 300, and 350K
