Meaning
A reaction profile is a simple graph showing the energy change which takes place as a reaction progresses.
About Reaction Profiles
- Reaction profiles can show the activation energy needed for a chemical reaction to begin.
- The reaction profile can be used to show whether a reaction is exothermic or endothermic.
Examples
 |
 |
| The reaction profile for an exothermic reaction can be identified by the fact that the products have less energy than the reactants. | The reaction profile for an endothermic reaction can be identified by the fact that the products have more energy than the reactants. |
