The fresh feed to an ammonia process contains 24.75% mole Nitrogen, 74.35% mole Hydrogen, and the balance inerts. The feed is combined with a recycle stream containing the same species, and the combined stream is fed to a reactor in which 0.25% single-pass conversion of nitrogen is achieved. The product pass through a condenser in which essentially all of the ammonia is removed and the remaining gases are recycled. However, to prevent build up of the inerts in the system, a purge stream must be taken off. The recycle stream contains 12.5% mole inerts. Calculate the overall conversion of Nitrogen, the ration n (moles purge gas/ mole of as leaving the condenser), and the ratio (moles fresh feed/ mole fed to the reactor)
