List-I (Processes/Reactions)		List-II (Catalyst)
A	$2S{O}_2(g)+O_2(g)\to 2S{O}_3(g)$	i	$Fe(s)$
B	$4N{H}_3(g)+5O_2(g)\to$$4NO(g)+6H_{2}O(g)$	ii	$Pt(s)-Rh(s)$
C	$N_2(g)+3H_2(g)\to 2N{H}_3(g)$	iii	$V_2{O}_5$
D	Vegetable oil $(l)+H_2\to$Vegetable ghee(s)	iv	$Ni(s)$

Choose the correct answer from the options given below :

• A. (A) - (III), (B) - (I), (C) - (II), (D) - (IV)
• B. (A) - (III), (B) - (II), (C) - (I), (D) - (IV)

Answer 1

Answer: (B)

Sol. $2S{O}_2(g)+O_2(g)\stackrel{V_2{O}_5}{\to }2S{O}_3(g)$ :
contact process
$4N{H}_3(g)+5O_2(g)\stackrel{Pt(s)-Rh(s)}{\to }4NO(g)+6H_{2}O(g)\text{ : }$
Ostwald's process
$N_2(g)+3H_2(g)\stackrel{Fe(s)}{\to }2N{H}_3(g);$ Haber's process
Vegetable oil $(l)+H_2(g)\stackrel{Ni(s)}{\to }$ vegetable ghee
Hydrogenation
