Solution

	List-II		List-II
A	${N}_{2}(g)+3{H}_{2}(g)\rightarrow 2{\mathrm{NH}}_{3}(g)$	III	${\mathrm{Fe}}_{x}{O}_{y}+{K}_{2}O+{\mathrm{Al}}_{2}{O}_{3}$
B	$\mathrm{CO}(g)+3{H}_{2}(g)\rightarrow {\mathrm{CH}}_{4}(g)+{H}_{2}O(g)$	IV	$\mathrm{Ni}$
C	$\mathrm{CO}(g)+{H}_{2}(g)\rightarrow \mathrm{HCHO}(g)$	I	$\mathrm{Cu}$
D	$\mathrm{CO}(g)+2{H}_{2}(g)\rightarrow {\mathrm{CH}}_{3}\mathrm{OH}(g)$	II	$\mathrm{Cu}/\mathrm{ZnO}-{\mathrm{Cr}}_{2}{O}_{3}$

{N}_{2}(g)+3{H}_{2}(g)\rightarrow 2{\mathrm{NH}}_{3}(g)

is Haber process and catalyst used are

{\mathrm{Fe}}_{x}{O}_{y}+{K}_{2}O+{\mathrm{Al}}_{2}{O}_{3}

${H}_{2}O+C\rightarrow {H}_{2}+\mathrm{CO}$

The product of this is called synthesis gas and can be extremely useful in bonding with metallic heterogeneous catalysts to produce different organic compounds.
