Liquids A and B from an ideal solution in the entire composition range. At 350 K, the vapor pressures of pure A and pure B are 7    Pa and 12  Pa, respectively. The composition of the vapor in equilibrium with a solution containing 40 mole percent of A at this temperature is :

(a)

= 0.37; = 0.63

(b)

= 0.28; = 0.72

(c)

 = 0.76; = 0.24

(d)

 = 0.4; = 0.6
