Answer 1

CONCEPT:

Redox Reaction

A redox reaction is a chemical reaction in which oxidation and reduction occur simultaneously.
Oxidation: It is the process in which an element loses electrons, resulting in an increase in its oxidation state.
Reduction: It is the process in which an element gains electrons, resulting in a decrease in its oxidation state.
In a redox reaction, one substance is oxidized, and another is reduced.

EXPLANATION:

The given reaction is:
2 N₂O₅ ⇌ 4 NO₂ + O₂
In this reaction:
- Nitrogen in N₂O₅ has an oxidation state of +5.
- Nitrogen in NO₂ has an oxidation state of +4.
- Oxygen in O₂ is in its elemental state with an oxidation state of 0.
During the reaction:
- The oxidation state of nitrogen decreases from +5 in N₂O₅ to +4 in NO₂, indicating a reduction.
- The oxidation state of oxygen increases from -2 in N₂O₅ to 0 in O₂, indicating an oxidation.
Since both oxidation and reduction occur simultaneously, this reaction is classified as a redox reaction.

Therefore, the correct answer is Option 3: Redox reaction.
