I don’t know which reactant(s) and product(s) you mean — can you paste the chemical equation or name the compounds?

If you meant the common decomposition of potassium chlorate:
KClO3 → KCl + O2
then the oxidation numbers are:
- Reactant (KClO3): K = +1, Cl = +5, O = −2 (each)
- Products: KCl: K = +1, Cl = −1; O2: O = 0 (each)

So Cl goes from +5 → −1 (reduced), O from −2 → 0 (oxidized), and K stays +1.
