The total pressure exerted in ideal binary solution is given by P=P_(A

1.	The total pressure exerted in ideal binary solution is given by P=P_(A)^(@)X_(A)+P_(B)^(@)X_(B) where P_(A)^(@)&P_(B)^(@) are the respective vapour pressure of pure components and X_(A)&X_(B) are their mole fraction in liquid phase. And composition of the vapour phase is determined with the help of Datton's law partial pressure: Y_(A)=(P_(A)^(@)X_(A))/(P) If total pressure exerted in an ideal binary solution is given by P=(5400)/(60+30Y_(A))mm of Hg. The more volatile liquid is:
Answer» LIQUID A liquid B both are same it DEPENDS on the AMOUNT of A and B Answer :B
