\(100 \mathrm{kmol} / \mathrm{h}\) of an \(8 \mathrm{~mol} \%\) naphthalene \(-92 \mathrm{~mol} \%\) phenol mixture at \(40^{\circ} \mathrm{C}\) is fed to a continuous crystallizer. The crystallizer operates at \(33^{\circ} \mathrm{C}\). Data are in Figure 18-1.

a. What is the purity of crystals?

b. What is the approximate concentration of the final melt?

c. How many \(\mathrm{kmol} / \mathrm{h}\) of crystals are harvested, and what is the flow rate, \(\mathrm{kmol} / \mathrm{h}\), of the mother liquor?
