A liquid mixture of A and B shows positive deviation from Raoult’s law when

When A – B interactions are weaker than A – A and B – B interactions, then the mixture of A and B shows positive deviation ;Vapour pressure of the mixture is more than expected from Raoult's law;∆Vmix>0, ∆Hmix>0, ∆Smix>0, ∆Gmix<0 ;
