(D) The decomposition of $H_2O_2$ is represented as: $2H_2O_2(l) ightarrow 2H_2O(l) + O_2(g) + 	ext{Heat}$.$1$. It is an exothermic reaction because heat is released during the process.$2$. It is an example of auto-oxidation (or disproportionation) where the oxygen in $H_2O_2$ (oxidation state $-1$) is both oxidized to $O_2$ $(0)$ and reduced to $H_2O$ $(-2)$.$3$. It is an example of negative catalysis because substances like acetanilide or glycerol act as negative catalysts to slow down its decomposition.Therefore,all the given options are correct.

The decomposition of hydrogen peroxide is an example of
