Ammonia can be manufactured by the Haber process:
Conditions for haber process:
1. A temperature of 450 degree celcius
2. a pressure of 250 atm
3. the presence of iron catalyst.
Raw material in the Haber process = nitrogen and hydrogen
Nitrogen is extracted from liquid air through fractional distillation,
Hydrogen is produced from the cracking of petroleum.
Effect of temp on the yield of ammonia:
- A lower temperature increases the yield of ammonia and reduces the decomposition of ammonia to hydrogen and nitrogen. However, a lower temperature also results in a slow reaction.
Effect of pressure on the yield of ammonia:
- yield of ammonia increases under high pressure, thus increasing the rate of reaction.
