# What will occur if a catalyst is added to a reaction mixture?

Dec 28, 2017

Possibly nothing....

#### Explanation:

Catalysts are not magic; they can only work on a specific reaction. Catalysts generally reduce the activation energy of the reaction, so that the given reaction reaches equilibrium more quickly. Catalysts cannot change the position of the equilibrium....

You will note from the graph that the energy change of the reaction, i.e. $\Delta {E}_{\text{rxn}}^{\circ}$ is CONSTANT....
