It changes the equilibrium constant.

Vedclass · Answer

(A) catalyst does not change the equilibrium constant because it affects both the forward and backward reaction rates to the same extent.It provides an alternative reaction pathway with a lower activation energy,which increases the rate of reaction.It does not increase the average kinetic energy $(K.E.)$ of the molecules.Therefore,both $A$ and $D$ are not characteristics of a catalyst,but in the context of standard multiple-choice questions,$A$ is the most fundamental thermodynamic property that remains unchanged.

List-$I$	List-$II$
$A. N_{2(g)} + 3H_{2(g)} \rightarrow 2NH_{3(g)}$	$I. Fe_xO_y + K_2O + Al_2O_3$
$B. CO_{(g)} + 3H_{2(g)} \rightarrow CH_{4(g)} + H_2O_{(g)}$	$II. Ni$
$C. CO_{(g)} + H_{2(g)} \rightarrow HCHO_{(g)}$	$III. Cu$
$D. CO_{(g)} + 2H_{2(g)} \rightarrow CH_3OH_{(g)}$	$IV. Cu/ZnO - Cr_2O_3$
