Examples

catalysts are said to reduce the energy of activation during the transition phase of a reaction Source: Internet

For a chemical reaction to proceed at a reasonable rate, there should exist an appreciable number of molecules with translational energy equal to or greater than the activation energy. Source: Internet

Catalysts are substances which change the pathway (mechanism) of a reaction which in turn increases the speed of a reaction by lowering the activation energy needed for the reaction to take place. Source: Internet

Enzymes function by lowering the activation energy of the transition state of a chemical reaction, thereby enabling the formation of an otherwise less-favorable molecular intermediate between the reactant(s) and the product(s). Source: Internet

Given the small temperature range kinetic studies occur in, it is reasonable to approximate the activation energy as being independent of the temperature. Source: Internet

Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy. Source: Internet
