what are the economic importances of the haber process,solvay process,and contact process?

Question

thank you please can i have like 3 or more thanks

Answer 1

The Haber process combines nitrogen and hydrogen to form ammonia. Ammonia is mostly used itself as fertilizer. Ammonia reacts with oxygen by the Ostwald process to form nitric acid. Nitric acid is important in fertilizers, explosives, and making organic compounds for further chemical production.

The Solvay process is actually no longer of much importance. It is the multi-step reaction of calcium carbonate (limestone) and sodium chloride (salt) to form sodium carbonate (useful soda ash) and calcium chloride (almost useless co-product). It has been largely supplanted by surface mining of trona, which is a naturally occurring sodium carbonate.

The contact process makes sulfuric acid by combination with existing H2SO4 with SO3 to form pyrosulfuric acid, H2S2O7. Next, H2S2O7 reacts with water to form two molecules of H2SO4. So although you need a mole of H2SO4 to start, you get two back. The economic importance is that it is cheaper than the lead chamber process, which it replaced, and gives 100% H2SO4. The lead chamber process formed nitrosylsulfuric acid, O=N-SO3H, from nitrogen oxides, and that reacted with water to form H2SO4. The H2SO4 was only about 70%, though.

Answer 2

Haber process produces ammonia which is used as fertilizers for fir the agricultural and gardening industry.
Contact process produces sulphuric acid, it is need as a raw material in the manufactoring of a lot of substances.
