A single-stage, continuous steam distillation of 1-octanol at \(760.0 \mathrm{~mm} \mathrm{Hg}\) with liquid water present distills \(1.0 \mathrm{kmol} / \mathrm{h}\) of a feed of \(90.0 \mathrm{~mol} \% 1-\) octanol and the rest nonvolatile compounds. Distillate vapor is condensed, and two immiscible liquid layers form. Flow rate of the feed is \(1.0 \mathrm{kmol} / \mathrm{h}\). We desire to recover \(95.0 \%\) of 1 -octanol. Antoine coefficients for vapor pressure of 1-octanol and water are listed in Table 2-3 (pay attention to the units). Accurate vapor pressure data for water are listed in Table 8-1.

a. Find the operating temperature of the still.
b. Find the octanol mole fraction in the vapor leaving the still.
c. Find the moles of octanol recovered and the moles of water condensed in the distillate product.
