a$)$ A solution containing $6\mathrm{.}5$mol$\%$ ethanol, $5\mathrm{.}4$mol$\%$ acetic acid and balance water is fed to a separator at a rate of $120mo\frac{l}{h}.$ The separator operates at steady state. Three product streams, named as stream A$,$ B and C$,$ leave the separator in which $95$mol$\%$ of ethanol fed to the separator leaves in stream A and $5\%$ leaves in stream B$.$ Stream A and $B$ contain $15\%$ and $80\%$ of the acetic acid fed to the separator, respectively. About $70\%$ of the water fed to the separator leaves in stream C and $15\%$ in each of stream A and stream B$.$
