Zeolites are useful as catalysts in ........

Adam's catalyst is

In which of the following processes is platinum used as a catalyst?

Match the following:

$List-I$ (Process)	$List-II$ (Catalyst)
$(A)$ Ostwald's process	$(I)$ $NO$
$(B)$ Lead Chamber process	$(II)$ $Fe$
$(C)$ Deacon's process	$(III)$ $Pt/Rh$
$(D)$ Haber's process	$(IV)$ $CuCl_2$

The correct answer is:

Match the Column-$I$ with Column-$II$ and mark the appropriate choice.

Column-$I$	Column-$II$
$A. V_2O_5$	$i. \text{Conversion of } SO_2 \text{ to } SO_3$
$B. Ni$	$ii. \text{Hydrogenation of oils}$
$C. MnO_2$	$iii. \text{Preparation of } O_2 \text{ from } KClO_3$
$D. Fe$	$iv. \text{Haber's process}$

The number of correct statements about modern adsorption theory of heterogeneous catalysis from the following is ..........
$A.$ The catalyst is diffused over the surface of reactants.
$B.$ Reactants are adsorbed on the surface of the catalyst.
$C.$ Occurrence of chemical reaction on the catalyst's surface through formation of an intermediate.
$D.$ It is a combination of intermediate compound formation theory and the old adsorption theory.
$E.$ It explains the action of the catalyst as well as those of catalytic promoters and poisons.
