Question

$3KCl{O}_3⟶2KCl+3O_2$
The above reaction is a disproportionation reaction. If true enter 1, else enter 0.

Answer 1

$Cl$ of $KCl{O}_3$ ($O.N=+5$) is reduced to ${Cl}^{-}$ and $O$ of $KCl{O}_3$ ($O.N=-2$) is oxidised to $O_2$.
Therefore, the reaction is a redox reaction but not disproportionation.
