Vedclass · Answer

(D) The decomposition of potassium chlorate $(KClO_3)$ is a standard laboratory method for the preparation of oxygen gas.The reaction is represented as: $2KClO_3(s) \xrightarrow{MnO_2, \Delta} 2KCl(s) + 3O_2(g)$.In this reaction,manganese dioxide $(MnO_2)$ acts as a catalyst to lower the activation energy,allowing the decomposition to occur at a lower temperature.

Which of the following catalysts is used in the decomposition of $KClO_3$?
