Answer:

Is this not a redox reaction ....?

Explanation:

#KClO_3(s) + Delta stackrel(MnO_2)rarrKCl(s) + 3/2O_2(g)uarr#

#Cl^(VI+)# is reduced to #Cl^(-I)#

Oxide anion is oxidized to dioxygen gas..... These reactions are often catalysed by a little #"manganese(IV+) oxide"# as an oxygen transfer reagent.
