A binary mixture of acetone (1) and acetonitrile (2) is flashed at temperature 340 K and 115 kPa. The overall mole fraction of acetone in the feed was 0.75. Determine the equilibrium mole fraction of liquid and vapor phase formed. Assume that Raoult's law applies. Antoine equation for acetone and acetonitrile are given below (saturation pressure is in kPa and temperature is in K)
In P₁ˢᵃᵗ = 14.3916 - (2795.82/ T - 43.15)
In P₂ˢᵃᵗ= 14.7258 - (3271.24/ T - 31.30)
