What are the conditions for Ostwald process?
Typical conditions for the first stage, which contribute to an overall yield of about 98%, are: pressure is between 4–10 standard atmospheres (410–1,000 kPa; 59–150 psi) and. temperature is about 870–1,073 K (600–800 °C; 1,100–1,500 °F).
What catalyst is used in Ostwald process?
The Ostwald process is used to produce nitric acid. Ammonia is the feedstock for this reaction. It is reacted with oxygen and water using a platinum catalyst to produce nitric acid. The reaction is exothermic.
Why platinum is used in Ostwald process?
Most catalytic oxidations of ammonia follow the Ostwald process. In this process, platinum is used as the catalyst. This gas is adsorbed by the water, which allows the reaction to occur to reduce some of it back into nitric oxide and the rest into the desired product of nitric acid.
How nitric acid is prepared by Ostwald process write the conditions required to get Max product?
Step1: In this step ammonia is oxidised in the presence of oxygen (atmospheric) in the presence of catalyst Pt/Rh gauze catalyst at 500K temperature and 9 bar pressure. As a result of the above reaction nitric oxide and water is formed. Step2: Nitric oxide formed from step 1 readily combined with oxygen to give NO2.
What is Ostwald process in chemistry class 12?
Ostwald’s process is a chemical process to convert ammonia into nitric acid in two stages. In stage1 ammonia is oxidized to form nitric oxide and nitric dioxide and in the second step the nitrogen dioxide is allowed to dissolve in water and finally nitric acid is formed.
Which of the following pressure is used in Ostwald’s process of manufacture of nitric acid?
Step1: In this step ammonia is oxidised in the presence of oxygen (atmospheric) in the presence of catalyst Pt/Rh gauze catalyst at 500K temperature and 9 bar pressure. As a result of the above reaction nitric oxide and water is formed.
How is nitric acid manufactured by Ostwald’s process?
Nitric acid is most commonly manufactured by Ostwald process. 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.
How is nitric acid prepared by Ostwalds process?
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.
Which catalyst is used in oxidizing NH3 in Ostwald process?
Platinum
Catalyst used in Ostwald process is Platinum. During ostwald process ammonia is converted to nitric acid in 2 stages.
