8. A sample of dry ice (solid CO2) is cooled to -100 °C, and is set on a table at room temperature (25 °C). At what temperature is the rate of sublimation and deposition the same? (Assume pressure is held constant at 1 atm). Given the following data about CO2: Triple point - 57°C, 5.11 atm Critical point - 31°C, 73 atm Sublimes at -78.5°C, 1 atm The solid is the denser phase Construct a simplified phase diagram for CO2 а. b. Estimate the vapor pressure of CO2 at 0°C At 10 atm pressure and -50°C, is CO2 a liquid? Explain. С.
