Match List - I with List - II

Choose the correct answer from the options given below

Let us match each reaction with its industrial catalyst:

(A) $$N_2(g) + 3H_2(g) \rightarrow 2NH_3(g)$$

This is the Haber process for ammonia synthesis. The catalyst used is finely divided iron with promoters potassium oxide and aluminium oxide:

$$\text{Catalyst: } Fe_xO_y + K_2O + Al_2O_3 \rightarrow \textbf{(III)}$$

(B) $$CO(g) + 3H_2(g) \rightarrow CH_4(g) + H_2O(g)$$

This is the methanation reaction (Sabatier reaction). The catalyst used is nickel:

$$\text{Catalyst: Ni} \rightarrow \textbf{(IV)}$$

(C) $$CO(g) + H_2(g) \rightarrow HCHO(g)$$

The synthesis of formaldehyde from synthesis gas uses a copper catalyst:

$$\text{Catalyst: Cu} \rightarrow \textbf{(I)}$$

(D) $$CO(g) + 2H_2(g) \rightarrow CH_3OH(g)$$

This is methanol synthesis. The catalyst used is a mixture of copper, zinc oxide, and chromium oxide:

$$\text{Catalyst: Cu/ZnO-Cr}_2\text{O}_3 \rightarrow \textbf{(II)}$$

The correct matching is: A - III, B - IV, C - I, D - II.

Therefore, the correct answer is Option C.
