2 moles of liquid a (p/AA=100torr) and 3 moles of liquid B(pB⁰=150torr) form a solution having vapour pressure of 120 torr. based upon this observation one can conclude :-
a. interactions between like molecules> those between unlike molecules
b. interactions between like molecules< those between unlike molecules
c. interactions between like molecules= those between unlike molecules
d. ΔSₘᵢₓ =0, ΔVₘᵢₓ=0
