Select the compound that will have the lower equilibrium vapor pressure based on predicted intermolecular forces. pentane (C5H12) phosphorus tribromide

Organic molecules change phases above 300°C. O True O False

Ethanol, with ΔHvap = 40.5 kJ mol-1, has a higher ΔHvap than methanol, which is 35.2 kJ mol-1, due to its larger size and greater intermolecular forces. Because the ΔHvap for ethanol is larger, we would expect that for the two liquids to reach the same vapor pressure, the temperature for ethanol would have to be higher. If the vapor pressure is 0.0992 atm at 27.3 °C, what would the temperature be when the vapor pressure is 4.52 atm?

What is Δq for the vaporization of 50.0 g of Compound A (76.03 g/mol;  ΔHvap is 31.6 kJ/mol)?

In addition to filling in the blanks below, show all of your work for this problem on paper for later upload. The heat of vaporization of isopropanol is 44.0 kJ/mol. The vapor pressure of isopropanol at 400 torr is 67.8 °C. Calculate the normal boiling point of isopropanol. Enter your value in the first box and an appropriate unit of measure in the second box.
