Solution Preview

<br>The activation energy is the minimum amount of energy that the reacting molecules must pocess before the reaction will proceed.
<br>
<br>Chemical reactions take place with changes in energy. This energy change is symbolised as DH, the HEAT OF REACTION. The energy change is often discerned by the senses as heat.
<br>
<br>DH is the DIFFERENCE between the energy of the products and the energy of the reactants.
<br>

    But the stability of the carbon - carbon and carbon - oxygen bonds blocks the spontanous reaction. So one has to ignite it ( i.e. a high activation energy ).

  • Ammonia and Oxygen

    However, if we add a catalyst, then we can overcome the effect of LeChatalier's principle. How is this? Because a catalyst lowers the activation energy for a reaction. It lowers the "energy hump" required to get reactants to form products.
