A column with $60$ equilibrium stages and a partial reboiler is being operated at total reflux to separate a mixture of A and $B$ where $A$ is the more volatile component and the relative volatility is constant at a value of $1\mathrm{.}1.$ We are measuring a distillate concentration that is $95$mol$\%A.$ The column has a total condenser and saturated liquid reflux. Determine composition A in the bottom stream

Correct Answer:

$0\mathrm{.}0536$
