Match List-I with List-II:
| List-I (Industrial process) | List-II (Application) | ||
|---|---|---|---|
| (a) | Haber’s process | (i) | $\text{HNO}_3$ synthesis |
| (b) | Ostwald’s process | (ii) | Aluminium extraction |
| (c) | Contact process | (iii) | $\text{NH}_3$ synthesis |
| (d) | Hall-Heroult process | (iv) | $\text{H}_2\text{SO}_4$ synthesis |
Choose the correct answer from the options given below:
(1) (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
(2) (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
(3) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
(4) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
Show Answer
Answer: (3)
Solution
(a) Haber’s process is used for $\text{NH}_3$ synthesis. (b) Ostwald’s process is used for $\text{HNO}_3$ synthesis. (c) Contact process is used for $\text{H}_2\text{SO}_4$ synthesis. (d) In Hall-Heroult process, electrolytic reduction of impure alumina can be done (Aluminium extraction).
