The diagram represents the Haber process for the manufacture of ammonia from nitrogen and
hydrogen.
heat exchanger
N, + H,-
catalytic
converter
condenser
NH,
What is the purpose of the heat exchanger?
A to cool the incoming gas mixture to avoid overheating the catalyst
B to cool the reaction products and separate the NH, from unused N2 and H2
c to warm the incoming gas mixture and shift the equilibrium to give more NH3
D to warm the incoming gas mixture and speed up the reaction
