Why do Nitrogen dioxide and hydrogen gas react with each other?

In summary, Nitrogen dioxide and hydrogen gas react with each other due to their unstable electron configurations. The chemical equation for the reaction is 2NO2 + 4H2 → 2NH3 + 2H2O. This is a redox reaction, where electrons are transferred between reactants to form products. The end products are ammonia (NH3) and water (H2O). The reaction occurs through a series of steps, where NO2 is first reduced to NO, then NO is further reduced to NH3, and finally, H atoms combine to form H2O.

Why don't they tend to stay as they are?

Nitrogen is more electronegative, and when reacted, can form a polar bond, in which it basically takes the electron from the hydrogen molecule. This is more stable and thermodynamically favorable.

You could also say that it minimizes the free energy, which is the indicator of whether a reaction will occur spontaneously.
 

Related to Why do Nitrogen dioxide and hydrogen gas react with each other?

1. Why do Nitrogen dioxide and hydrogen gas react with each other?

Nitrogen dioxide (NO2) and hydrogen gas (H2) react with each other because they both have unstable electron configurations. Nitrogen dioxide has an unpaired electron, while hydrogen gas has two unpaired electrons. When they come into contact, they form a chemical bond to achieve more stable electron configurations.

2. What is the chemical equation for the reaction between Nitrogen dioxide and hydrogen gas?

The chemical equation for the reaction between Nitrogen dioxide and hydrogen gas is 2NO2 + 4H2 → 2NH3 + 2H2O.

3. What type of reaction occurs between Nitrogen dioxide and hydrogen gas?

The reaction between Nitrogen dioxide and hydrogen gas is a redox reaction, also known as an oxidation-reduction reaction. This means that electrons are transferred between the reactants to form the products.

4. What are the products of the reaction between Nitrogen dioxide and hydrogen gas?

The products of the reaction between Nitrogen dioxide and hydrogen gas are ammonia (NH3) and water (H2O).

5. How does the reaction between Nitrogen dioxide and hydrogen gas occur?

The reaction between Nitrogen dioxide and hydrogen gas occurs through a series of steps. First, the NO2 molecule is reduced by gaining two electrons from the H2 molecule to form NO. Then, NO is further reduced by gaining two more electrons from H2 to form NH3. Finally, the remaining H atoms combine with each other to form H2O.
