Thermite process

Vedclass · Answer

(B) The $Haber$ process uses iron as a catalyst for the synthesis of ammonia. The $Ostwald$ process uses platinum/rhodium gauze as a catalyst for the production of nitric acid. The $Contact$ process uses vanadium pentoxide $(V_2O_5)$ as a catalyst for the production of sulfuric acid. The $Thermite$ process is a pyrotechnic composition of metal powder and metal oxide,which produces an exothermic reaction without the use of a catalyst.

List-$I$ (Reaction)	List-$II$ (Catalyst)
$A$. $N_{2(g)} + 3H_{2(g)} \longrightarrow 2NH_{3(g)}$	$I$. $Ni$
$B$. $2H_{2(g)} + O_{2(g)} \longrightarrow 2H_2O_{(l)}$	$II$. $Pt$
$C$. $CO_{(g)} + 3H_{2(g)} \longrightarrow CH_{4(g)} + H_2O_{(g)}$	$III$. $ZnO-Cr_2O_3$
$D$. $CO_{(g)} + 2H_{2(g)} \longrightarrow CH_3OH_{(g)}$	$IV$. $Fe$

In which of the following processes is a catalyst $NOT$ used?
