Vapour pressure of pure acetone and chloroform at 328 K are 741.8 mm Hg and 632.8 mm Hg respectively. Assuming that they form ideal solution over the entire range of composition, plot $P_{\text{total}}$, $P_{\text{chloroform}}$ and $P_{\text{acetone}}$ as a function of $x_{\text{acetone}}$. The experimental data observed for different compositions of mixtures is :Plot this data also on the same graph paper. Indicate whether it has positive deviation or negative deviation from the ideal solution.
