100 kmol/hr of fresh feed to an ammonia process contains 22.25 mole% nitrogen, 66.75 mole% hydrogen, and the balance argon. The feed is combined with a recycle stream containing the same species, and the combined stream is fed to a reactor where 25% single-pass conversion is achieved. The products pass through a condenser where all the ammonia is removed, and the remaining gases are recycled. To prevent buildup of the argon in the system, a purge stream is bled off this recycle stream. The purge stream contains 20.969 mole% argon. What is the overall conversion of nitrogen?


a. 47.54
b. 36.54

c. 41.06

d. 53.42
