Consider an ethanol/methanol solution at 300K with chi_method = 0.5. (The vapor pressures of pure ethanol and methanol at 300 K are respectively 65.8 mmHg and 140 mmHg.) a) Will the mole fraction of methanol in the vapor phase be greater, less than or equal to 0.5? Explain. b) What is the vapor pressure of the solution? c) What is the mole fraction of ethanol in the vapor?
