To decrease the activation energy of a reaction

Vedclass · Answer

(D) $1$. $A$ catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.$2$. It functions by providing an alternative reaction pathway with a lower activation energy $(E_a)$.$3$. By lowering the activation energy, a greater fraction of reactant molecules possess sufficient energy to cross the energy barrier, thereby increasing the reaction rate.$4$. Therefore, the correct role is to decrease the activation energy of a reaction.
