Question

Liquid 'M' and liquid 'N' form an ideal solution. The vapour pressures of pure liquids 'M' and 'N' are 450 and 700 mm Hg respectively at the same temperature. Then correct statement is: ( Xm=mole fraction of 'M' in solution; Xn=mole fraction of 'N' in solution; ym=mole fraction of 'M' in vapour phase; yn=mole fraction of 'N' in vapour phase ). (A) (Xm/Xn) > (ym/yn) (B) (Xm/Xn) = (ym/yn). (C) (Xm-Xn) < (Xn-yn). (D) (Xm/Xn) < (ym/yn)​
