Is condensation reversible above critical pressure?

[flygyd]

I have a 50% carbon dioxide and 50% nitrogen gas mix at 1800psig, 70*F. Is there a reference source for the dewpoint of the CO2 in that mix?

Assuming the temperature falls below that dewpoint and the CO2 condenses, will it return to a mix as the temperature is raised?

thanks, kw

Is my question totally off the wall?
