For an ideal binary solution with P_A⁰> P_B⁰,then which relation between X_A and Y_A is correct
a) X_A=Y_A
b)X_A >Y_A
c)X_A < Y_A
d)X_A/X_B<Y_A/Y_B

relative lowering of Vapour pressure is = mole fraction ,
therefore as PÂ°_A>PÂ°_B

thus XÂ°_A>XÂ°_A thus (b) is correct

No
You are wrong [17]

options C and D both are correct

answer is D only

Explain how ?

for option c
Ya=Xa Pa⁰/P_t
and Pa⁰ is greater than P_t so.......

for option D
Ya/Yb=(Xa/Xb) Pa⁰/Pb⁰
and PÂ°A>PÂ°B so .........

thank you :-)
