Short explanation
The Haber process is an industrial method for synthesizing ammonia (NH₃) from nitrogen (N₂) and hydrogen (H₂) gases. This process occurs under high temperature (approximately 450 degrees Celsius) and high pressure (around 200 atmospheres), using an iron catalyst to enhance the reaction rate. Nitrogen is sourced from the air, while hydrogen is typically derived from methane or natural gas. The reaction is reversible, allowing for the recycling of unreacted gases, which increases efficiency. Ammonia produced through this process is crucial for creating nitrogen-based fertilizers, supporting agricultural productivity.
