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 ...

Enzymes are primarily proteins, although some RNA molecules called ribozymes also exhibit enzymatic activity. Enzymes are biological catalysts that lower the activation energy of chemical reactions, ...
