What happens when a mixture of ammonia and oxygen is passed over platinum gauze heated to 800?

What happens when ammonia gas mixed with oxygen passes over heated platinum catalyst? What is the utility of this reaction in industry?

What happens when ammonia oxygen mixture is passed over heated platinum?

When NH3 + 02 is passed over heated platinum at about 800°C then H20 and NO along with heat is formed as product the NO further forms N02 which is brown in colour while H20 rises off as steam.

What happens when ammonia gas is mixed with oxygen gas in the presence of platinum catalyst?

Ammonia reacts with oxygen in the presence of a platinum catalyst to give nitric oxide and water,…

What will you observe when ammonia is oxidized in the presence of platinum at 800 degree Celsius and the product is exposed to air?

Answer: (i) Yes. Ammonia bums in oxygen with a greenish yellow flame producing water vapour and nitrogen. (ii) Ammonia, when reacts with oxygen in presence of platinum (as catalyst) at 800°C, ammonia is oxidised to nitric oxide (NO). This is called catalytic oxidation of ammonia.

What happens when mixture of NH3 and air is passed?

Answer: This process is a part of the Ostwald process for manufacture of nitric acid. The mixture forms nitrogen oxide and water upon reaction.

What happens when ammonia is catalytically heated with air?

The catalytic oxidation of ammonia occurs when ammonia and oxygen are combined in the presence of high heat and a catalytic metal. The ammonia is then oxidized into nitric oxide. In a separate container, oxygen continues oxidizing the nitric oxide into nitrogen dioxide gas, which is adsorbed by water.

When a mixture of furan and ammonia is passed over heated alumina at 753K What is obtained?

A None of above. When a mixture of Furan and ammonia is passed over heated alumina at 753K. a) Pyrrole is obtained.

What happens when ammonia catalytically heated with air?

What happens when ammonia combines with oxygen?

Ammonia reacts with oxygen to form nitrogen and water.

How does ammonia react with oxygen?

Ammonia and oxygen without catalyst | NH3 + O2 → N2 + H2O. With supply of heat, ammonia reacts with oxygen and produce nitrogen gas and water as products. Nitrogen of ammonia is oxidized to nitrogen gas from -3 oxidation state to 0 oxidation state.

What happens when ammonia is oxidized?

What is the reaction between ammonia and oxygen?

What happens when ammonia reacts with platinum?

The oxidation of the ammonia is sufficiently exothermic to maintain the platinum (or palladium) catalyst red hot without subsequent heating. Various oxides of nitrogen are formed which may also react with excess ammonia to form nitrates and nitrites (the downstream gas looks smokey). What happens when carbon dioxide is passed through ammonia?

What happens when ammonia reacts with oxygen without catalyst?

If ammonia react with oxygen without catalyst, nitrogen and water are given. Both compounds are not toxic. Whem ammonia react with oxygen in the presence of Pt catalyst, nitric oxide (NO) and watwe are given. At levels of 100 ppm, nitric oxide is immediately dangerous to life and health.

What happens when gaseous ammonia is passed over solid copper(II)oxide?

When gaseous ammonia is passed over solid copper (II)oxide at high temperatures, nitrogen gas is formed. Also This N2 gas is not pure as it would be in the heating of NaN3 like compounds. (VERY IMPORTANT FOR NEET)

What is the diameter of a platinum gauge catalyst?

The Platinum Gauze Catalyst. The catalyst at Stanford-le-Hope consists of hexagonal gauze sheets, 36 inches in diameter, woven by Johnson Matthey from rhodium-platinum wire of 0.003 inch gauge into an 80 mesh screen.
