What is the purpose of the Haber process?

The Haber process is specifically designed to synthesize ammonia by reacting nitrogen gas (N₂) with hydrogen gas (H₂). This reaction is crucial because ammonia is a key ingredient in fertilizers, which play a significant role in agriculture by providing essential nutrients to crops. The process occurs under high temperature and pressure with the presence of an iron catalyst, which facilitates the combination of the two gases. By converting atmospheric nitrogen into ammonia, the Haber process effectively contributes to food production and has had a profound impact on global food security. The other options do not pertain to the primary function of the Haber process, which is distinctly focused on ammonia production.
