Lowers the activation energy

Vedclass · Answer

(A) catalyst provides 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 at a given temperature.This leads to an increase in the rate of the reaction.Catalysts do not change the thermodynamic properties like Gibbs free energy change $(\Delta G)$ or enthalpy change $(\Delta H)$ of the reaction.
