Q. 3. A binary solution is described by the one-parameter equation: GE RT = A(x, - x) Where A is a constant. At 50 C and x=0.30, the partial pressures of the two composnents in the vapor are pi=105.3 mm Hg, p2=288 mm Hg, respectively. The saturation pressure of pure components at 50 C: P, sat=228 mm Hg, P2sat= 380 mm Hg. Calculate total pressure, P and vapor phase composition (y1, y2) of this system at 50 C. (3 points)
