why is 800°C temperature used for preparation of nitric acid using ostwald process
Answers
Answer:
The Ostwald process converts ammonia to nitric acid and involves two steps. In step 1, ammonia is oxidized to form nitric oxide and also nitrogen dioxide. Then in step 2, the nitrogen dioxide that was formed is absorbed in water. This in-turn forms nitric acid.
Ostwald process is one of the most common methods or chemical process used for the manufacturing of nitric acid. The process was developed in the year 1902 by a German chemist named Wilhelm Ostwald. He was later awarded the Nobel Prize in 1909 for his research.
Ostwald process has gained popularity over the years as it is the easiest way to produce nitric acid which is also widely used in many areas such as in the production of fertilizers as well as inorganic and organic nitrates or nitro compounds
