Decomposition of potassium chlorate can be represented a s: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/258f4fe9fae101c68c76553445a6adfd-.png" /> overset+5Cl is reduced to overset-1Cl and overset-2O is oxidised to overset0O2, hence reaction is a redox reaction.

Q. Assertion: Decomposition of potassium chlorate is an example of redox reaction.
Reason: There is no change in the oxidation number of potassium in decomposition of potassium chlorate.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

Decomposition of potassium chlorate can be represented a s :

$Cl + 5$ is reduced to $Cl - 1$ and $O - 2$ is oxidised to $O 0_{2},$ hence reaction is a redox reaction.
