• A. I - a, II - b, III - d, IV - c
• B. I - b, II - c, III - a, IV - d
• C. I - a, II - d, III - c, IV - b
• D. I - a, II - c, III - b, IV - d

Answer 1

The correct option is B I - b, II - c, III - a, IV - d

Contact process is used for production of $H_{2}S{O}_4$.
$2S{O}_2+O_2\to 2S{O}_3$
This reaction is one of the stages of Contact process.

In Ostwald's process ammonia is converted to nitric acid in 2 stages.
$4N{H}_3+5O_2\stackrel{{800}^{\circ }C/Pt}{\to }4NO+6H_{2}O$
$2NO+O_2\to 2N{O}_2$
$3N{O}_2+H_{2}O\to 2HN{O}_3+NO$

Deacon's process is based on oxidation of $HCl$.
$4HCl+O_2\underset{450-{500}^{\circ }/V_2{O}_5}{\overset{{3230}^{\circ }C/CuC{l}_2}{\to }}2C{l}_2+2H_{2}O$

Haber's process is the main industrial procedure to produce $N{H}_3$.
$2N_2+3H_2\stackrel{Fe+Mo}{\to }2N{H}_3$
