(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 c. At 10 atm pressure and -50°C, is CO2 a liquid? Explain.

4 You are given the phase diagram shown and asked to determine several properties of the substance. First, find the normal melting point and boiling point. Pressure in atm 1.00- 0.75- 0.50- 0.25- 0 -50 solid -25 liquid -B- gas 0 25 Temperature, °C D 50 E This data does not extend to high enough pres- sure to determine the normal melting and boiling points of this substance. The normal melting point is ~-10 degrees Cel- sius, and the normal boiling point -50 degrees Celsius. This substance has a triple point so the normal melting and boiling points are the same.
A substance in its liquid state has vapor pressures of 0.0518 atm at -85°C and 0.0773 atm at -80°C. In its solid state, it has sublimation pressures of 352 Pa at -112 °C and 35 Pa at -126.5°C. Determine the triple point pressure (atm).
