The Haber process (also known as Haber–Bosch process) is the reaction of nitrogen and hydrogen, over an iron-substrate, to produce ammonia . The Haber process is important because ammonia is difficult to produce, on an industrial scale. Even though 78.1% of the air we breathe is nitrogen, the gas is relatively inert due to the strength of the triple bond that keeps the molecule together. It was not until the start of the twentieth century that this method was developed to harness the atmospheric abundance of nitrogen to create ammonia, which can then be oxidised to make the nitrates and nitrites essential for the production of nitratefertilizer and munitions.
