Vedclass · Answer

(D) catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.It functions by providing an alternative reaction pathway with a lower $Activation \ energy$ $(E_a)$.It does not alter the $Gibbs \ energy$ $(\Delta G)$,$Enthalpy$ $(\Delta H)$,or the $Equilibrium \ constant$ $(K_{eq})$ of the reaction.Therefore,the correct option is $D$.
