5.6 Reaction Energy Profile

3 practice questions

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:
Products lower than reactants means the reaction is:
$E_a$ is measured from:
