Vedclass · Answer

(D) The thermal decomposition of potassium permanganate $(KMnO_{4})$ at $513 \ K$ $(240^{\circ}C)$ is given by the reaction:$2 \ KMnO_{4} \xrightarrow{\Delta} K_{2}MnO_{4} + MnO_{2} + O_{2}$In the product $K_{2}MnO_{4}$ (potassium manganate),the oxidation state of manganese $(Mn)$ is $+6$.The electronic configuration of $Mn^{6+}$ is $[Ar] \ 3d^{1}$.Since there is one unpaired electron,the compound $K_{2}MnO_{4}$ is paramagnetic.Additionally,$K_{2}MnO_{4}$ is known for its characteristic green colour.

Potassium permanganate on heating at $513 \ K$ gives a product which is :
