The graph of vapor pressure vs. temperature for three liquids, trichloromethane, tetrachloromethane and water, are shown below. CHCI, cC4 H20 1000 800- 60아 400 200 O 20 40 60 80 Temperature (°C) Estimate the temperatures at which the vapor pressure of CCl is 400. torr and 700. torr. (The dash lines are for your reference.) Use these values to calculat the enthalpy of vaporization, AHvap, of CCl. 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 CHCI3 and in liquid CCl4? Describe how you know from the molecular structural level. Vapor Pressure (tom)

Question

Need help with a Chemistry Problem! Unsure how to complete this practice Problem

The graph of vapor pressure vs. temperature for three liquids, trichloromethane, tetrachloromethane and water, are shown below. 1000 CHCI, C4 H20 800 600 400 - 200 60 80 100 Temporature (°C) 20 40 Estimate the temperatures at which the vapor pressure of CC14 is 400. torr and 700. torr. (The dash lines are for your reference.) Use these values to calculate the enthalpy of vaporization, AHvap, of CCla. 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. Vapor Pressure (tom)
