Recall nitrogen and hydrogen as the raw materials for the Haber process. (Chemistry only)

The Haber process is an industrial method for synthesizing ammonia, which is crucial for producing nitrogen-based fertilizers. The raw materials for this process are nitrogen and hydrogen. Nitrogen is primarily sourced from the air, while hydrogen is typically derived from methane or natural gas through steam reforming. Under high temperature and pressure conditions, these gases react over an iron catalyst to form ammonia. This process is essential for meeting agricultural demands, as ammonia can be further processed into various fertilizers that enhance crop yields.
