Question

Hello, need help w/vapor pressure problem!

The graph of vapor pressure vs. temperature for three liquids, trichloromethane, tetrachloromethane and water, are shown below. 1000 CHCI, CCa H20 B00 600 400- 200 20 40 60 80 100 Temporature (°C) Estimate the temperatures at which the vapor pressure of CC14 is 700. torr. (The dash lines are for your reference.) Use these values to calculate the enthalpy of vaporization, AHvap, of CCl4. Using information provided in the graph, rank the overall strength of intermolecular forces in the three liquids, from the weakest to the strongest. Describe how you know. What intermolecular forces are present in liquid CHCI; and in liquid CCl,? Describe how you know from the molecular structural level. torr and electronegativity ofC = 2.5, CI = 3.0. C-H bond is considered nonpolar. Vapor Pressure (tom)
