Activation energy is the minimum energy required for a chemical reaction to occur. By lowering the activation energy, a greater proportion of reactant molecules have sufficient energy to overcome the energy barrier and react, thus increasing the reaction rate. Catalysts are not consumed in the overall reaction.
In a chemical reaction, catalyst changes
