Vedclass · Answer

(C) 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 $(E_a)$.By lowering the activation energy, a greater fraction of reactant molecules possess sufficient energy to cross the energy barrier, thereby increasing the reaction rate.It does not change the enthalpy $(\Delta H)$ of the reaction or the equilibrium constant.
