The maximum value 
can hold is 1 , and hence the maximum value of 
should come out to be 512 
of 
, which is less than the value of 
observed 
of 
). Therefore, positive deviation from Raoult's law is observed. This implies that A-A interactions and B-B interactions are stronger than A-B interactions.
As we know, for a system not obeying Raoult's law and showing positive deviation,
