69. For an ideal binary liquid solution with PX > Pwhich relation is correct if X, is mole fraction of A inliquid phase and Y. is mole fraction of A in vapourphase?(1) YAxb(3) ya/yb>xa/xb(4) ya/yb |

Answer» P A ′ =P A 0 ⋅X A =P M ⋅Y A
P B ′ =P B 0 ⋅X B =P M ⋅Y B
∴ P B 0
P A 0
⋅ X B
X A
= Y B
Y A
∵ P B 0
P A 0
>1∴ X B
X A
< Y B
Y A
