5.6 Reaction Energy Profile
Notes
An energy profile shows reactants, products, the transition state (top), activation energy $E_a$ and $\Delta H$.
- Exothermic: products lower than reactants.
Practice
On an energy profile, the peak is the:
Highest energy arrangement.
Products lower than reactants means the reaction is:
Energy is released.
$E_a$ is measured from:
The energy barrier for the forward reaction.
