Vedclass · Answer

(D) The decomposition of potassium chlorate $(KClO_3)$ is a slow process. When manganese dioxide $(MnO_2)$ is added,it acts as a positive catalyst. $A$ catalyst provides an alternative reaction pathway with a lower activation energy,thereby increasing the rate of the reaction. The balanced chemical equation is: $2KClO_3 \xrightarrow{MnO_2} 2KCl + 3O_2$.

When $KClO_3$ is heated,it decomposes into $KCl + O_2$. If some $MnO_2$ is added,the reaction goes much faster because
