- Exothermic
3. Hess' Law
- If a reaction can take place by more than one route and the initial and final conditions are the same, the total enthalpy change is the same for each route
- The enthalpy change that accompanies the formation of one mole of an ionic compound from its gaseous ions under standard conditions
