Question:
At 39.9°C, a solution of ethanol (x1 = 0.9006, P*1 = 130.4 Torr) and isooctane (P*2 = 43.9 Torr) forms a vapor phase with 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 pressure that the solution would have if it were ideal.
