The critical temperature (Tc) and critical pressure ( pc) of are 30.98°C and 73 atm respectively. Can (g) be liquefied at 32°C and 80 atm pressure?
It does not matter that how high temperature or high-pressure is CO2 at; it cannot be liquified above 30.98o and 73 atm. Hence, it cannot be liquified at 32o and 80 atm pressure.
