QUESTION:

NO is a pollutant emitted by motor vehicles. It is formed by the reaction:

(a)Β \(\mathrm{N}_{2}(g)+\mathrm{O}_{2}(g) \rightarrow 2 \mathrm{NO}(g)\)

Once in the atmosphere, NO (through a series of reactions) adds one oxygen atom to form \(\mathrm{NO}_{2}\). \(\mathrm{NO}_{2}\) then interacts with UV light according to the reaction:

(b)Β \(\mathrm{NO} 2(\mathrm{~g}) \underset{\mathrm{UV} \text { light }}{\longrightarrow} \mathrm{NO}(g)+\mathrm{O}(g)\)

These freshly formed oxygen atoms then react with \(\mathrm{O}_{2}\) in the air to form ozone \((\mathrm{O}_{3})\), a main component of Smog:

(c)Β \(\mathrm{O}(g)+\mathrm{O}_{2}(g) \rightarrow \mathrm{O}_{3}(g)\)

Classify each of the preceding reactions (a, b, c) as a synthesis, decomposition, single-displacement, or double-displacement reaction.

ANSWER:

Solution 93P

Here, we have to find out the type of each reaction.

Synthesis:Β When two or more molecules combine together to form a new compound is called synthesis.

Decomposition :It is a chemical reaction where a single compound splits into two or more simple substances under suitable conditions.

Single displacement reaction:Β It is a chemical reaction where an element reacts with a compound and takes the place of another element in that compound.

Double displacement reaction:
