Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Industrial conversion of N2 to NH3 is carried out by which process?
A
Howarth
B
Borlaug-Bodirsky
C
Erisman et al
D
Haber-Bosch
Explanation: 

Detailed explanation-1: -In the Haber process, “the atmospheric nitrogen (N2) is converted to ammonia (NH3) by reacting it with hydrogen (H2)”. Here a metal catalyst is used and high temperatures and pressures are maintained.

Detailed explanation-2: -The Haber-Bosch process is a process that fixes nitrogen with hydrogen to produce ammonia-a critical part in the manufacture of plant fertilizers. The process was developed in the early 1900s by Fritz Haber and was later modified to become an industrial process to make fertilizers by Carl Bosch.

Detailed explanation-3: -The Haber-Bosch process is the primary method in producing ammonia from nitrogen and hydrogen. Ammonia produced, utilized mainly as fertilizers, currently responsible for approximately 1.8% of carbon dioxide global emissions (The Royal Society, 2020).

Detailed explanation-4: -The Haber-Bosch process, which converts hydrogen and nitrogen to ammonia, could be one of the most important industrial chemical reactions ever developed. The process made ammonia fertilizer widely available, helping cause a world population boom as yields from agriculture increased rapidly in a short time.

Detailed explanation-5: -The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. The catalyst is actually slightly more complicated than pure iron.
