Match the following :
(a) Pure nitrogen (i) Chlorine
(b) Haber process (ii) Sulphuric acid
(c) Contact process (iii) Ammonia
(d) Deacon's process (iv) Sodium azide or Barium azide
Which of the following is the correct option ?
(a) (b) (c) (d)
(1) (I) (ii) (iii) (iv)
(2) (ii) (iv) (i) (iii)
(3) (iii) (iv) (ii) (i)
(4) (iv) (iii) (ii) (i)
Answers
(a) Pure nitrogen - (iv) Sodium azide or Barium azide
(b) Haber process - (iii) Ammonia
(c) Contact process - (ii) Sulphuric acid
(d) Deacon's process - (i) Chlorine
Option (4) (iv) (iii) (ii) (i) is correct.
(a) Pure nitrogen is obtained by heating Sodium azide or Barium azide. Chemical equation is given by: Ba(N3)2 --> Ba + 3N.
(b) the nitrogen fixation process is the Haber process but is also used in the production of ammonia. The process is also called a Haber-Bosh process.
(c) the process in which the sulphuric acid is produced in high concentrations is called the contact process.
(d) the process in which the chlorine is obtained as the product during the manufacturing of alkalis is called the Deacon's process. Chemical equation is given by: HCl + O2 -> 2Cl2 + 2H2O.
Upon matching the given options-
(a) Pure nitrogen can be prepared by the thermal decomposition of Sodium azide or Barium azide.
(b) Haber's process is used for the preparation of Ammonia.
(c) Contact process is used for the preparation of Sulphuric acid.
(d) Deacon's process is used for the preparation of Chlorine gas.
Therefore, the correct option is (4)
