Question 1

A liquid has a molar heat of vaporization of 22.7 kJ/mol. Its normal boiling point is 459 K. What is the vapor pressure, in mmHg, at 70 °C?
◦ 102 mmHg
◦ 7.48 mmHg
◦ 56.8 mmHg
◦ 742 mmHg
◦ 580 mmHg

Question 2

A liquid has a normal boiling point of 78 °C and its vapor pressure is 400 mmHg at 50 °C. To compute the molar heat of vaporization, one needs:
