Seeing How Catalysts Speed Up Reactions
Catalysts speed up reactions by lowering the activation energy of a reaction. They do this in one of two ways:
✓ Providing a surface and orientation that makes a reactant more likely to hit the right part of another reactant to break/make a bond
✓ Providing an alternative mechanism (series of steps for the reaction to go through) that has a lower activation energy
