The Haber process for ammonia production requires high pressure and low temperature as the optimum conditions.
However, this is very slow although the percentage yield is very high (90%+).
Commercially, a pressure of approximately 200 atmospheres and a temperature of 400 degrees C are used. The reaction is faster but only produces about 15% ammonia. This 15% is constantly drawn off and the unused gases recycled.
A catalyst of iron used as it speeds up the rate of reaction.
