Vedclass · Answer

(D) In the reaction $MnO_2 + 2KOH + \frac{1}{2}O_2 \longrightarrow K_2MnO_4 + H_2O$:The oxidation state of $Mn$ in $MnO_2$ is $+4$.The oxidation state of $Mn$ in $K_2MnO_4$ is $+6$.The oxidation state of $O$ in $O_2$ is $0$,and in $K_2MnO_4$ and $H_2O$ it is $-2$.Since the oxidation state of $Mn$ increases from $+4$ to $+6$ (oxidation) and the oxidation state of $O$ decreases from $0$ to $-2$ (reduction),this is an intermolecular redox reaction.Specifically,it is a combination reaction where $MnO_2$ reacts with $KOH$ and $O_2$ to form a single product $K_2MnO_4$ along with water.Therefore,it fits the category of a thermal combination redox reaction. The correct option is $D$.

Assign $A, B, C, D$ from the given type of reaction.
$MnO_2 + 2KOH + \frac{1}{2}O_2 \longrightarrow K_2MnO_4 + H_2O$
