It can be represented on an energy level diagram. The diagram shows that when a catalyst is used, the activation energy is reduced. This makes more of the collisions successful at a given temperature.

to make sulphuric acid Adding a catalyst lowers the activation energy. This increases the number of molecules with the minimum kinetic energy required for a reaction to take place. This increases ...

THE vapour phase hydrogenation of benzene has been widely studied, but considerable doubt still remains about the activity of various catalysts and the activation energy of this highly exothermic ...
