Hallo dear ,
_______________________________

b. Which two gases react together?
Answer : dihydrogen and dinitrogen

d. Why is the mixture passed over iron?
Answer : The iron is needed because the spacing between the iron atoms just allows the nitrogen atoms to slide in between them, this helps split the nitrogen molecules into individual atoms.

e.What happens to the unreacted
nitrogen and hydrogen?
Answer : The unreacted nitrogen and hydrogen, together with the ammonia, pass into a cooling tank. ... The unreacted hydrogen and nitrogen gases are recycled by being fed back through pipes to pass through the hot iron catalyst beds again.

f. Why is the manufactured ammonia stored at high pressure?
Answer : Anhydrous ammonia is a liquid when compressed or cooled. It is stored under pressure to prevent vaporization so a large volume can be available for use.
