JUST ANSWER B AND C I ALREADY GOT A

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.
