What is the catalyst of N2(g)+3H2(g) to give(double arrow) 2NH3(g)?
https://en.wikipedia.org/wiki/Haber_process
The catalyst for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) is typically iron, in the form of finely divided iron or iron salts. This reaction is known as the Haber-Bosch process and is used industrially to produce ammonia.
In order to determine the catalyst for this reaction, one way is to refer to established scientific literature or textbooks. Information about catalysts for specific reactions is often documented in these sources. Additionally, you can also conduct experiments or research studies to identify catalysts by examining the reaction conditions and studying the catalytic behavior of different substances.
It's important to note that while iron is the most commonly used catalyst for this reaction, other catalysts such as ruthenium, osmium, and various iron-based compounds have also been studied for their catalytic activity in the synthesis of ammonia.
