1. Construct the x-y equilibrium diagrams for the three systems using the given values of relative volatility.

2. Show in the x-y plane the three equilibrium curves

3. From the visual appreciation on the diagram of the previous numeral, indicate what is the relative "ease" with which each binary mixture would be separated.

\begin{tabular}{|c|c|} \hline BINARY SYSTEM & RELATIVE VOLATILITY \\ \hline n-Hexane (1)-heptane(2) & 2.64 \\ \hline n-Hexane (1)/p-Xylene & 7.32 \\ \hline p-Xylene(1)/m-Xylene(2) & 1.0204 \\ \hline \end{tabular}
