What is Activation Energy?
- It is the initial energy given out that is used to break the bonds of the reactants.
- It represents the minimum energy needed for the reaction to happen.
- It is only shown on the energy diagrams for exothermic reactions.
Activation Energy and Cataysts:
- Catalysts lower the activation energy because it provides an alternative reaction pathway.
- This is shown by the lower curve on the graph because less initial energy is needed for the reaction to happen.
- The overall enthalpy change remains the same even with a catalyst.
