One hundred moles per minute of an equimolar mixture of methyl ethyl ketone (1) and toluene (2) are flashed from 760 mm Hg to 460 mm Hg at 75°C. You know, experimentally, that the infinite dilution activity coefficient of methyl ethyl ketone in toluene is 1.44 at this temperature. Likewise, you know that the experimental value for the infinite dilution activity coefficient of toluene in methyl ethyl ketone is 1.33 at this temperature. Solve for the composition and amount of each equilibrium phase as a result of the flash if

(a) The liquid is treated as an ideal solution 

(b) The liquid is treated as modeled by the 2-parameter Margules equation
