CO2 has Tc = 38.98 °C and Pc = 73 atm. How many phases of CO2 coexist at i. 50 °C and 73 atm ii. 20 °C and 50 atm. |
|
Answer» i. 50 °C and 73 atm represent a condition for CO2 above its Tc . Therefore, under this condition CO2 exists only as single phase. ii. 20° C and 50 atm represent a condition for CO2 below its Tc . Therefore, under this condition two phases of CO2 , namely, liquid and gas can coexist. |
