3. True or False. a. The relation d In P/ dT AvapH / RT² should not be applied to solid-liquid transitions. b. The relation d In P/ dT AvapH / RT2 should be applied to liquid-vapor transitions. c. The relationd In P / dT = AvapH / RT² should be applied near the critical point. 4. Some vapor pressures of a certain substance are the following: 1327 48.48 1427 Temp (°C) P (Torr) 1227 1527 1627 19.72 107.2 217.7 408.2 a. Generate the equation of the best-fit line from a plot of In P (Torr) vs. 1/T. b. Find the average AvapH over this temperature range. c. Estimate the liquid's normal boiling point. с. 5. The sublimation pressure of CO2 is 138.85 K and 158.75 K is 1.33x10-3 bar and 2.66x10-2 bar, respectively. Estimate the molar enthalpy of sublimation of CO2.
