Extracted text: The trimerization 3A(g) → A3(g.l) is carried out isothermally and without pressure drop in a PFR at 298 K and 2 atm. As the concentration of A3 increases down the reactor and Ag begins to condense. The vapor pressure of A3 at 298 K is 0.5 atm. If an equal molar mixture of A and inert, I, is fed to the reactor at what conversion of A will A3 begin to condense?
