$D$. for either thermal combination redox reaction or thermal decomposition redox reaction.

Vedclass · Answer

(D) The given reaction is: $2KMnO_4 \xrightarrow{\Delta} K_2MnO_4 + MnO_2 + O_2 \uparrow $In this reaction,$KMnO_4$ undergoes thermal decomposition upon heating to produce $K_2MnO_4$,$MnO_2$,and $O_2$.The oxidation state of $Mn$ changes from $+7$ in $KMnO_4$ to $+6$ in $K_2MnO_4$ and $+4$ in $MnO_2$.The oxidation state of $O$ changes from $-2$ in $KMnO_4$ to $0$ in $O_2$.Since a single reactant breaks down into multiple products upon heating and involves a change in oxidation states,it is classified as a thermal decomposition redox reaction.Therefore,the correct assignment is $D$.

Assign $A, B, C, D$ from the given type of reaction:
$2KMnO_4 \xrightarrow{\Delta} K_2MnO_4 + MnO_2 + O_2 \uparrow $
