3. Normal physical state of substance - 2Standard enthalpy change of reactionThe enthalpy change when the amount of reactants shown in the balanced equation react to give products (standard conditions)
- 3Standard enthalpy change of formationEnthalpy change when 1 mole of a compound is formed from its elements (standard conditions)
- 4Standard enthalpy change of combustionEnthalpy change when 1 mole of a substance is burnt in excess oxygen. The reactants and products must be in their natural states (standard conditions)
- 5Enthalpy change of solutionEnthalpy change when one mole of a substance dissolves in a solvent to form an infinitely dilute solution (standard conditions)
- 6Enthalpy change of atomisationEnthalpy change when one mole of gaseous atoms is formed from its element (standard conditions)
- 7Enthalpy change of hydration (of an anhydrous salt)Enthalpy change when 1 mole of hydrated salt is formed from 1 mole of anhydrous salt
- 8Hess's LawTotal enthalpy change in a chemical reaction is independent of the route taken given the initial and final conditions are the same.
