Surface Chemistry

Solution:

Haber-Bosch process is used for the synthesis of ammonia.

$N _{2}+3 H _{2} \rightleftharpoons 2 NH _{3} ; \Delta H=-92.0\, kJ$

The best catalyst for this reaction is highly porous finely divided iron containing small amounts of promoters usually molybdenum or oxides of potassium and aluminium.
