1. The aeration of water is an important
industrial operation. Determine the liquid diffusion coefficient of oxygen in
an infinitely dilute solution of water at 288 K using (a) the Wilke Chang
equation and (b) the HaydukLaudie equation.
2. A silicon wafer is doped with
phosphorus. From Figure 24.8, the nominal value of the diffusion coefficient
for phosphorus in silicon at 1316 K is 1 cm2/s
and at 1408 K is . Determine the
value of the diffusion coefficient at 1373 K.
