The pure N2(g) required for the ammonia synthesis reaction will be taken from air. This is done with an air liquifaction plant. Suggest a way this might work based on knowledge of phase equilibrium. To do this first consider air to be made up of only N2 (78 mole %), O2 (21%), and Ar (1%) and estimate the mole fractions of each in both liquid and gas phases if one mole of air at 300 K as well as 4 atm total pressure is cooled to 65 K in the same volume.
Which of the following is a buffer?
