A n-hexane (1)/n-octane (2) equimolar mixture is originally in its compressed liquid state undergoes flashing via isothermal decompression (T = 348 K) to the point where L=V (i.e., where the total mole fractions of vapor and liquid are equal).

(a) Express P in terms of saturation pressures, P=sqrt(P_1^sat*P_2^sat

(b) Is flash calculation possible for this problem? Logically explain.

(c) Find x1, y1, x2 and y2. Get Antoine parameter from the attached table.
