7. The vapor pressure of isooctane is 75.0 torr at 34.0 °C. What is the normal boiling point Given: Heat of vaporization of isooctane = 33.8 kJ/mol

17. A substance with stronger intermolecular forces is expected to have lower: A) molar mass B) chemical particles size C) surface tension D) vapor pressure

What is represented by A on the phase diagram?

Answer the following questions concerning vapor pressure. a) Why doesn't a change in the surface area of a liquid cause a change in the equilibrium vapor pressure?     b) What effect does increasing the temperature have on the equilibrium vapor pressure of a liquid? Explain!

The normal boiling point of a liquid is 82.5 oC. Also, the equilibrium vapor pressure of this liquid is 320 torr at 37.0 oC. Determine the molar enthalpy of vaporization of the liquid in kJ/mol (kilo-Joule/mol) with 3 significant figures.
