$2 KClO_3 \xrightarrow{\Delta} 2 KCl + 3 O_2$

Vedclass · Answer

(A) The thermal decomposition of potassium permanganate $(KMnO_4)$ is given by the reaction: $2 KMnO_4 \xrightarrow{\Delta} K_2MnO_4 + MnO_2 + O_2$. Here,$X$ is manganese dioxide $(MnO_2)$. $MnO_2$ acts as a catalyst in the decomposition of potassium chlorate $(KClO_3)$ to produce oxygen gas. The reaction is: $2 KClO_3 \xrightarrow{MnO_2, \Delta} 2 KCl + 3 O_2$. Therefore,the correct option is $A$.

Potassium permanganate on heating gives potassium manganate,oxygen and $X$. For which of the following reactions,$X$ is used as a catalyst?
