Answer to Question #329909 in Chemistry for Mark

Question

The fresh feed to ammonia synthesis reactor contains nitrogen, hydrogen and 2.0 mole 

% inerts. The mole ratio of H2:N2 is 3:1. The product stream consists of pure 

ammonia. The conversion in the reactor is 15 %, a recycle stream is used and in order 

to avoid build-up of inerts, a purge is withdrawn. The rate of purge stream is adjusted 

to keep inert concentration in the recycle stream at 8 mole per cent. Calculate the 

moles of ammonia produced.
