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_("total"),p_("chloroform") and p_("acetone")` as a function of `x_("acetone")`. The experimental data observed for different composition of mixture is :
`{:(100xx x_("acetone"),0,11.8,23.4,36.0,50.8,58.2,64.5,72.1),(p_("acetone")//"mm Hg",0,54.9,110.11,202.4,322.7,405..9,454.1,521.1),(p_("chloroform")//"mm Hg",632.8,548.1,469.4,359.7,257.7,193.6,161.2,120.7):}`
Plot this data also on the same graph paper. Indicate whether it has positive devition or negative deviation from the ideal solution.

Explanation

`{:(x_("acetone"),0.0,11.8,23.4,36.0,50.8,58.2,64.5,72.1),(p_("acetone")//"mm Hg",0,54.9,110.1,202.4,322.7,405.9,454.1,521.1),(p_("chloroform")//"mm Hg",632.8,548.1,469.4,359.7,257.7,193.6,161.6,120.7):}`

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