Answer

	Column $I ($Catalyst$)$		Column $II ($Process$)$
$(i)$	Ni in the presence of hydrogen	$(c)$	Vegetable oil to ghee
$(ii)$	$Cu_2Cl_2$	$(d)$	Sandmeyer reaction
$(iii)$	$V_2O_5$	$(b)$	Contact process
$(iv)$	Finely divided iron	$(e)$	Haber’s Process
$(v)$	$TiCl_4 + Al (CH_3)_3$	$(a)$	Zieglar Natta catalyst

Explanation:
Catalyst $\rightarrow $ Process
Ni in presence of $H_{2 }\rightarrow $ Vegetable oil to ghee
$Cu_2Cl_{2 }\rightarrow $ Sandmayer reaction
$V_2O_{5 }\rightarrow $ Contact process
Finely divided iron $\rightarrow $ Haber’s process
$TiCl_{4 }+ Al(CH_3)_{3 }\rightarrow $ Zieglar Natta catalyst
