As we have learnt,

 

Condition of ideality -

Interaction between A - A; B - B are similar to A - B Interactions.

eg. Hexane + Heptone

Benzene + Toluere

- wherein

\Delta H_{mix}= 0

\Delta V_{mix}= 0

\Delta H - Change \: in\: enthalpy

\Delta V - Change \: in\: volume

 

 

 

Fact.


Option 1)

 \DeltaHmixing < 0 (zero)              
 

Option 2)

\DeltaHmixing > 0 (zero)            
             

Option 3)

 A-B interaction is stronger than      
    A-A and B-B interactions       
 

Option 4)

A-A, B-B and A-B interactions      
    are identical
