Question

Write down the reaction when Ammonia reacts with atmospheric oxygen in the presence of catalysts.

Answer 1

Chemical reactions are the chemical changes in which reactants transform into products by bond-making or bond-breaking or both between different atoms or molecules. When such a reaction is expressed in terms of symbols and formula, it gives us a chemical equation.

Complete step by step answer:
Catalytic oxidation of ammonia occurs when ammonia and oxygen are combined in the presence of high heat and a catalytic metal. Ammonia is then oxidized into nitric oxide. In a separate container, oxygen continues oxidizing the nitric oxide into nitrogen dioxide gas, which is absorbed by water.
When ammonia reacts with atmospheric oxygen in the presence of catalysts. The following reaction will happen.
$4N{H_{3}} + 5{O_2}\;\xrightarrow{{\dfrac{{Pt}}{{1100\;K}}}}\;4NO + 6{H_2}O$
In this reaction, nitrogen oxide is formed. In this reaction oxidation takes place.

Commissioned by the Mughal emperor, Shah Jahan, in memory of his favorite wife, Mumtaz Mahal, the Taj once had a pearly white exterior. But now it has changed in parts if not in whole, to various shades of yellow, brownish-black and green.
The Taj Mahal has become a matter of concern because pollutants in the air are discoloring its white marble.
It is the most beautiful place in India and it will be a tragedy if something bad happens to it.
The color of the Taj Mahal has changed from white to yellow because of the oxide of sulfur and nitrogen dissolve in rainwater and form acid (known as acid rain), and when this acid rain falls on it, then the color changes from white to yellow.
It is the acid rain that is most dangerous for the monument. Indeed, the inadvertent emission of sulfur dioxide, due to road traffic, causes acid rain.
This rain colors the Taj Mahal yellow, and thus tarnishes it, and worse, it erodes it.

Note: Haber process is used for producing ammonia. The reaction involved in this process can be given as follows: ${N_2} + 3{H_2} \rightleftharpoons 2N{H_3} + Q\,kcal$ .
Now for understanding the conditions that are the most favorable for this process, we need to understand the changes that are involved with this process.
1.The formation of ammonia using Haber’s Process involves the release of energy. This means that the formation of ammonia is an exothermic process.
2.In Haber’s Process, 4 moles of reactants form 2 moles of product. Hence the number of moles of the product formed is less than the number of reactants.
