(D) $1$. In the Haber process, the reaction is $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)$.$2$. Finely divided iron $(Fe)$ acts as the catalyst for this reaction.$3$. Molybdenum $(Mo)$ or a mixture of oxides like $Al_2O_3$ and $K_2O$ is added to increase the efficiency of the iron catalyst.$4$. $A$ substance that increases the activity of a catalyst is called a promoter.$5$. Therefore, $Al_2O_3$ acts as a promoter.

List-$I$ (Catalyst)	List-$II$ (Process)
