Vapour pressures 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_("total") P_("chloroform")`, and `P_("acetone")` as a function of `x_("acetone")` . The experimental data observed for different compositions of mixture is :

Plot this data also on the same graph paper. Indicate whether it has positive deviation or negative deviation from the ideal solution.

Explanation

The plot for `P_("total")` dips downwards, hence the solution shows negative deviation from the ideal behaviour.
