Question

The decomposition of $KCl{O}_3$ to $KCl$ and $O_2$ on heating is an example of:

• A. intramolecular of redox change
• B. intermolecular redox change
• C. decomposition or auto redox change
• D. None

Answer 1

The correct option is A intramolecular of redox change

In an intramolecular redox reaction, the molecule of a single substance undergoes oxidation-reaction by the process decomposition.
An example is the thermal decomposition of $KCl{O}_3$ into $KCl$ and $O_2$. In this case, chlorine is reduced to -1 state and oxygen is oxidized to zero states.
