The critical temperature `(T_(c))` and critical pressure `(p_(c))` of `CO_(2)` are `30.98^(@)C` and 73 atm respectively. Can `CO_(2) (g)` be liquefied at `32^(@)C` and 80 atm pressure ?

Text Solution

Verified by Experts

No, the gas cannot be liquefied at `32^(@)C` because this temperature is above the critical temperature of `30.98^(@)C`. The effect of pressure is insignificant above the critical temperature.
