As we learned

 

Negative deviation from Raoult's Law behaviour -

When the pressure exerted by vapours of mixture is less than that in case of ideal behaviour.

- wherein

P_{T}< P_{A}^{0}x_{A}+ P_{B}^{0}x_{B}

 

 There is hydrogen bond between two molecules of sulphuric acid and between two molecules of water, but there is ion dipole interaction
between sulphuric acid and water. Ion dipole interaction is stronger than hydrogen bond so solution shows negative deviation from Raoult’s
law.


Option 1)

Negative deviations from Raoult’s law

Option 2)

Positive deviations from Raoult’s law

Option 3)

Ideal properties

Option 4)

The applicability of Henry’s law
