Vedclass · Answer

(D) catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. $1$. It alters the rate of reaction by providing an alternative pathway with lower activation energy. $2$. It helps in reaching the equilibrium state faster,but it does not change the equilibrium constant. $3$. $A$ catalyst cannot initiate a reaction that is thermodynamically impossible. $4$. It does not affect the average kinetic energy of the molecules,as that is a function of temperature. Therefore,options $A$,$B$,and $C$ are characteristics,while $D$ is not.

List-$I$ (Catalyst)	List-$II$ (Process)
$A$. $Ni$ in presence of $H_2$	$1$. Ziegler-Natta catalyst
$B$. $Cu_2Cl_2$	$2$. Contact process
$C$. $V_2O_5$	$3$. Hydrogenation of vegetable oils
$D$. Finely divided iron	$4$. Sandmeyer reaction
$E$. $TiCl_4 + Al(CH_3)_3$	$5$. Haber process
	$6$. Decomposition of $KClO_3$
