Q1

Liquid A and B form an ideal solution. The vapour pressure of pure liquids A and B are \(350\) and\(750\)mm Hg respectively at the same temperature. If \({\mathrm{x}}_{\mathrm{A}}\) and \({x}_{B}\) are the mole fraction of A and B in solution while \({\mathrm{y}}_{\mathrm{A}}\) and \({y}_{B}\) are the mole fraction of A and B in vapour phase then

a

\(\frac{{x}_{A}}{{x}_{B}}<\frac{{y}_{A}}{{y}_{B}}\)

b

\(\frac{{x}_{A}}{{x}_{B}}=\frac{{y}_{A}}{{y}_{B}}\)

c

\(\frac{{x}_{A}}{{x}_{B}}>\frac{{y}_{A}}{{y}_{B}}\)

d

\(\left({\mathrm{x}}_{\mathrm{A}}-{\mathrm{y}}_{\mathrm{A}}\right)<\left({\mathrm{x}}_{\mathrm{B}}-{\mathrm{y}}_{\mathrm{B}}\right)\)
