Generation of distillation curves for systems with constant relative volatility is fairly straightforward and an excellent learning experience. Generate distillation curves in Figure 8-10 for a benzene (A), toluene (B), and cumene (C) system with \(\alpha_{\mathrm{AB}}=2.4, \alpha_{\mathrm{BB}}=1.0\), and \(\alpha_{\mathrm{CB}}=0.21\). Operation is at total reflux.

a." Mole fraction of A in the reboiler is 0.006735 , and mole fraction of B is 0.003469 .
b.* Mole fraction of \(\mathrm{A}\) in the reboiler is 0.001 , and mole fraction of \(\mathrm{B}\) is 0.009 .
c. Mole fraction of \(\mathrm{A}\) in the reboiler is 0.0003 , and mole fraction of \(\mathrm{B}\) is 0.0097
Remember \(\Sigma(\) mole fractions in the still pot \()=1.0\).
*Solution is shown in Figure 8-10.
