Exothermic!
Gosh. I had to change two answers which said "Endothermic"

Exothermic reactions give out heat. some examples of exothermic reactions are : 1)burning fuel in a fire 2)the addition of acid to water 3)the thermite reaction(this one is quite a sight) 4)the haber process of producing ammonia Endothermic reactions take in heat from their environment. some examples of endothermic reactions are: 1)an ice cube melting 2)depressurising a can(responsible in part why deodorant feels cold) 3)dissolving ammonium nitrate in water 4)decomposition of mercury (II) oxide(this requires a lot of heat)
The Haber process (also called the Haber-Bosch process) is the nitrogen fixation reaction of nitrogen gas and hydrogen gas over an enriched iron or ruthenium catalyst, which is used to produce ammonia. It's main use is in fertilizers, color compounds and N-polymers like nylon.N2 + 3H2 --> 2NH3(exothermic)
the haber process was invented by Fritz haber in 1908
Iron serves as a catalyst in the Haber process, facilitating the production of ammonia from nitrogen and hydrogen. The iron catalyst helps to lower the activation energy of the reaction, allowing it to proceed at a faster rate under milder conditions. This increases the efficiency of the ammonia synthesis reaction.
In the Haber process, ammonia is separated from the unreacted nitrogen and hydrogen gases by compressing the reaction mixture. This causes ammonia, being a soluble gas, to liquefy and separate from the remaining gases. This process helps to increase the concentration of ammonia and improve the overall efficiency of the reaction.
the Haber process is endothermic. Energy to make the reaction take place must come from something.

Have you heard of Haber-Bosch process of production of ammonia. This is an example of the question you asked. If we apply the required heat in the beginning of the reaction we do not need to apply it again as its exothermic reversible reaction and will use the heat to continue the reaction. But the rate of reaction is not increased.
A low temperature is not used in the Haber process because the reaction between nitrogen and hydrogen to form ammonia is an exothermic reaction, meaning it releases heat. Using a higher temperature allows for a higher reaction rate, but temperatures that are too high can lead to decreased ammonia yield due to the reverse reaction occurring.
its ya nanna :)
Yield in the Haber process can be maximised by using low temperatures (as the synthesis of ammonia is endothermic) and high pressures (as it promotes the forward reaction as more moles of gas are on the reactants side). However, low temperatures mean a slow reaction rate so compromised temperatures of 300 degrees celsius must be used.
its Fe- iron. It is used as a catalyst to speed up the exothermic reaction between N2 and H2 to make NH3.

The Haber process.
No, the Haber process to make ammonia can be reversed
