Ncert Exercises & Solutions

Match the catalysts given in Column I with the processes given in Column II.

Column I - (Catalyst)		Column II - (Process)
A.	Ni in the presence of hydrogen	1.	Contact process
B.	Cu₂Cl₂	2.	Vegetable oil to ghee
C.	V₂O₅	3.	Sandmeyer reaction
D.	Finely divided iron	4.	Haber's process
		5.	Decomposition of KClO₃

Codes

HINT: In the Haber process, iron is used as a catalyst.

Explanation:

The catalyst with there process is as follows:

Catalyst	Process
A. Ni in the presence of hydrogen	Vegetable oil to ghee
B. $C u_{2} C l_{2}$	Sandmeyer reaction
C. $V_{2} O_{5}$	Contact process $S O_{2} \overset{V_{2} O_{s}}{\to} S O_{3}$
D. Finely divided iron	Haber's process $N_{2} + 3 H_{2} \overset{F e}{\to} 2 N H_{3}$
