Vedclass · Answer

(D) An auto-catalytic reaction is one in which one of the products formed acts as a catalyst for the reaction itself.In the reaction between oxalate ions and permanganate ions:$5C_2O_4^{2-} + 2MnO_4^{-} + 16H^{+} \longrightarrow 10CO_2 + 2Mn^{2+} + 8H_2O$The $Mn^{2+}$ ions produced in the reaction act as an auto-catalyst, significantly increasing the rate of the reaction as the concentration of $Mn^{2+}$ increases.Therefore, option $(D)$ is the correct answer.

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