Use the Wilke-Chang theory to estimate infinite dilution Fickian diffusivity of ethanol in liquid water at \(293.16 \mathrm{~K}\) and of water in liquid ethanol. Data are available at www.engineeringtoolbox.com and https://www.cheric.org/research/kdb/ (click on Pure Component Properties and search compound of interest).

a. Calculate \(D_{\text {WE }}^{\circ}\) with a value of \(\varphi_{\mathrm{B}}=2.26\) for water

b. Calculate \(D_{\text {WE }}^{\circ}\) with a value of \(\varphi_{\mathrm{B}}=2.6\) for water

c. Calculate \(D_{\text {WEE }}^{\circ}\).
