10 mole of liquid 'A' and 10 mole of liquid 'B' is mixed in a cylindrical vessel containing a piston arrangement. Initially a pressure of 2 atm is maintained on the solution. Now, the piston is raised slowly and isothermally. Assuming A and B tobe completely miscible and forming an ideal solution. P_(A)^(@) = 0.6atm and P_(B)^(@) = 0.9 atm The minimum pressure for the existance of liquid solution is :

1.	10 mole of liquid 'A' and 10 mole of liquid 'B' is mixed in a cylindrical vessel containing a piston arrangement. Initially a pressure of 2 atm is maintained on the solution. Now, the piston is raised slowly and isothermally. Assuming A and B tobe completely miscible and forming an ideal solution. P_(A)^(@) = 0.6atm and P_(B)^(@) = 0.9 atm The minimum pressure for the existance of liquid solution is :
Answer» `0.6` ATM `0.8` atm `0.72` atm `0.9` atm Answer :C
