1.	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 compositions of mixture is :{:(100x x_("acetone"),0,11.8,23.4,36.0,50.8,58.2,64.5,72.1),(P_("acetone")//mm Hg,0,54.9,110.1,202.4,322.7,405.9,454.1,521.1),(P_("chloroform")//mm Hg,632.8,548.1,469.4,359.7,257.7,193.6,161.2,120.7):}From the question, we have the following data.
Answer» SOLUTION :`{:(x_("ACETONE"),0,11.8,23.4,0.360,0.508,0.582,0.645,0.721),(P_("acetone")//mm Hg,0,54.9,110.1,202.4,322.7,405.9,454.1,521.1),(P_("chloroform")//mm Hg,632.8,548.1,469.4,359.7,257.7,193.6,161.2,120.7),(P_("total"),632.8,603.0,579.5,562.1,580.4,599.5,615.3,641.8):}` It can be observed from the graph that the plot for the `P_("total")` to the solution curves DOWNWARDS. Therefore, the solution shows NEGATIVE deviation from the IDEAL behaviour.
