While the majority component of air is nitrogen (N2), the gas is
very unreactive because of its stability due to the triple bonds
that hold the nitrogen atoms together. Nitrogen gas is, therefore,
relatively unavailable for chemical reactions. One of the few ways
to “fix” nitrogen, making a nitrogen compound from the elemental
nitrogen in the atmosphere, is the Haber process (aka Haber - Bosch
process). In this reaction, nitrogen gas combines with hydrogen gas
to yield ammonia. The enthalpy...
