2 K overset text+5 Cl overset text -2 O3 arrowΔ 2K overset text-1Cl + 3 overset text 0 O2 Here one element of KClO3 is oxidised (O arrow O2) while the other is reduced ( overset text +5Cl arrow overset text-1Cl ) and hence, it is an example of intramolecular redox reaction.

Q. The decomposition of $K Cl O_{3}$ to $K Cl$ and $O_{2}$ on heating is an example of

intermolecular redox reaction

intramolecular redox reaction

autoredox reaction

none.

$2 K Cl +5 O_{3} -2 \to Δ 2 K Cl -1 + 3 O 0_{2}$
Here one element of $K Cl O_{3}$ is oxidised $(O \to O_{2})$ while the other is reduced $(Cl +5 \to Cl -1)$ and hence, it is an example of intramolecular redox reaction.
