Vapour pressures to pure acetone and chloroform at '328 K' are '741.8 mm Hg' and '632.8 mm' Hg respectively. Asśuming that they form ideal solution over the entire range of composition, The experimental data observed for different compositionis 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

total vapour.pressure is less than, the-ideal pressure. at all compositionis, if the solution exhibits negative deviation from Raouli.s law. . .
