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.

Column-$I$	Column-$II$
$A$. Haber's process for ammonia	$P$. Zeolite
$B$. Oswald's process for $HNO_3$	$Q$. $Fe$
$C$. Contact process for $H_2SO_4$	$R$. $V_2O_5$
$D$. Cracking of hydrocarbons	$S$. $Pt$ gauge

Which of the following is $NOT$ a characteristic of a catalyst?
