Developed into an industrial process by Carl Bosch, it requires a ratio of three volumes of hydrogen gas to one volume of nitrogen gas.
Osmium and uranium were the original catalysts for this reaction, but it now uses a cheaper iron oxide catalyst. It usually occurs at 200 atmospheres of pressure and 400-450 degrees Celsius, conditions which produce only a 15 percent yield, albeit in a very short span of time.

First used industrially during Germany in World War I, FTP, identify this reaction that produces ammonia.
