this is a preexam for this tuesday. Need help solving and understand please. Benzene has a heat of vaporization of 30.72 kJ/mol, and a normal boiling point of 80.1 deg. Celsius. At what temperature does benzene boil when the external pressure is 745 torr? well since I have a pressure, and i have what seems to be 2 temperatures, 1 i gotta find. I have to use the ln (p2/p1)= - Delta H vap / R (1/t2 - 1/t1) right?
