The Haber process is an industrial method used to synthesize ammonia from nitrogen and hydrogen gases. Developed by chemist Fritz Haber in the early 20th century, this process involves high temperatures and pressures, along with a catalyst, to facilitate the reaction. Ammonia produced through this method is essential for fertilizers, which play a crucial role in modern agriculture. The Haber process significantly increased the availability of nitrogen fertilizers, contributing to global food production. Its invention is considered one of the key advancements in chemical engineering, impacting both agriculture and the economy. However, it also raised concerns about environmental effects, such as pollution and over-fertilization.
