For a mixture of methanol (1) and methyl acetate (2): a.) Assume the mixture is found to obey Raoult’s law. At 60ºC and x1 = 0.25, what is the system pressure and the composition in the vapor? b.) Assume the mixture is found to obey Raoult’s law. At 60ºC and 90 kPa, what are the compositions in each phase? c.) Assume the mixture is NOT an ideal solution, and instead follows Modified Raoult’s law. It has been found experimentally that: ln(%) = 1.25x- - and ln(-) = 1.25x% -. At 100ºC and x1 = 0.75, what is the system pressure and the composition in the vapor?
