The vapour pressure of the solution of two liquids A(p^(@)=80mm) and B(p^(@)=120mm) is found to be 100mm of Hg when x_(A)=0.4. The result shows that:

Answer»

SOLUTION exhibits ideal behaviour
`DeltaH_(solution)lt0`
solution shows positive DEVIATION
solution will showpositive deviation for lower CONCENTRATION and negative deviation for HIGHER concentration

Solution :`P("Total")=0.4xx80+0.6xx120=104gt100mm` of `Hg`
