Given : The experimental data observed for different compositions of mixture is :
100 ×xacetone → 0 11.8 23.4 36.0 50.8 58.2 64.5 72.1 pacetone /mm Hg → 0 54.9 110.1 202.4 322.7 405.9 454.1 521.1
pchloroform/mm Hg →632.8 548.1 469.4 359.7 257.7 193.6 161.2 120.7
Solution :
ptotal(mm Hg) → 632.8 603.0 579.5 562.1 580.4 599.5 615.3 641.8
The graph of ptotal’ pchloroform’ and pacetone as a function of xacetone is in the attachment below .
From the graph it can be observed that the plot for the ptotalof the solution curves downwards.
Hence, the solution shows negative deviation from the ideal behaviour.
