1.	10 mole of liquid 'A' and 20 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 slowely and isothermally. Assume ideal behaviour of solution and A and B are completely miscible. P_(A)^(@) = 0.6 atm and P_(B)^(@) = 0.9 atm The pressure below which the evaporation of liquid solution will start, is
Answer» `0.5 ATM` `0.8atm` `0.77atm` `0.9atm` ANSWER :B
