For an ideal solution with P A ° P B °, which of the following is true?

Question

For an ideal solution with P A °> P B °, which of the following is true? (A)  chiA(l) = chi text A (V) (B)  chiA(l)> chiA(V) (C)  chi A (l)< chi A ( V ) (D) No relationship in their mole fraction

Tardigrade Admin · Accepted Answer

P A °> P B ° arrow Vapour pressure of ( A ) is more than ( B ) so mole fraction of ( A ) is more in vapour phase than liquid phase. Because vapours are more formed chiA(l)< chiA(v)

Q. For an ideal solution with $P_{A}^{\circ} > P_{B}^{\circ}$ , which of the following is true?

$χ_{A (l)} = χ_{A (V)}$

$χ_{A (l)} > χ_{A (V)}$

$χ_{A (l)} < χ_{A (V)}$

No relationship in their mole fraction

$P_{A}^{\circ} > P_{B}^{\circ} \to$ Vapour pressure of $(A)$ is more than $(B)$ so mole fraction of $(A)$ is more in vapour phase than liquid phase.
Because vapours are more formed
$χ_{A (l)} < χ_{A (v)}$

Q. For an ideal solution with PA∘​>PB∘​, which of the following is true?

χA(l)​=χA (V)​

χA(l)​>χA(V)​

χA(l)​<χA(V)​
