Short Answer TypeAnswer:
Among H,Cl and F, Hydrogen is least electronegtive while F is most electronegtive than Cl and H.
Thus F can withdraws more electron towards itslef more than Cl and H. So trifluoroacetic acid can easily lose the H+ ions. i.e.
trifluroacetic acid ionize to the larger extent .
Now more the ion produces the greater is the dpress ion of the freezing point
Hence, the depression of freezing point increase in order :
Acetic acid<trichloracetic acid < trifluroacetic acid
Vapour pressures of pure acetone and chloroform at 328 k are 741.8 nm Hg and 632.8 mm Hg respectively. Assuming that they form ideal solution over the entire range of composition, plot Ptotal , Pchlroform and Pacelone as a function of Xactone. The experimental date observed for different composition 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.
