JEE MainChemistrySolutionsMCQ+4 / −1
Liquid A and B form an ideal solution. The vapour pressures of pure liquids A and B are 350 and 750 mm Hg respectively at the same temperature. If xAx_AxA​ and xBx_BxB​ are the mole fraction of A and B in solution while yAy_AyA​ and yBy_ByB​ are the mole fraction of A and B in vapour phase, then,
  1. A
    (xA−yA)<(xB−yB)(x_A - y_A) \lt (x_B - y_B)(xA​−yA​)<(xB​−yB​)
  2. B
    xAxB=yAyB\frac{x_A}{x_B} = \frac{y_A}{y_B}xB​xA​​=yB​yA​​
  3. C
    xAxB<yAyB\frac{x_A}{x_B} \lt \frac{y_A}{y_B}xB​xA​​<yB​yA​​
  4. D
    xAxB>yAyB\frac{x_A}{x_B} \gt \frac{y_A}{y_B}xB​xA​​>yB​yA​​
