At 39.9 ◦C, a mixture of ethanol (x1 = 0.9060, p1 = 130.4 Torr) and isooctane ( p2 = 43.9 Torr) forms a vapor phase with molar fraction y1 = 0.6667 at a total pressure of 185.9 Torr. (a) Calculate the activity and activity coefficient of each component. (b) Calculate the total vapor pressure that the mixture would have if it were ideal.
