Reaction Profiles
- Classify a process as exo/endothermic from data or observations
- Draw a reaction energy profile, including the enthalpy change ΔH, activation energy Ea, transition state, and reference or unbonded states
- Relate enthalpy changes to changes in the relative strength of bonding in the reactants and products
Exo/Endothermic Processes
Exothermic Reaction: Release heat energy into the surroundings. More energy is in the reactants than the products.
Endothermic Reaction: Absorb heat energy from the surroundings. More energy is in the products than the reactants.
