- Module 3.2 - Physical Chemistry: Standard enthalpy changes
- enthalpy change
- the heat energy transferred in a reaction at constant pressure in KJ/mol
- Standard enthalpy change of combustion
- when 1 mole of a substance is completely burned in oxygen under standard conditions
- Standard enthalpy change of reaction
- when the reaction occurs in the molar quantities shown in the chemical equation, under standard conditions
- Standard enthalpy change of formation
- when 1 mole of a compound is formed from its elements in their standard states, under standard conditions
- Standard enthalpy change of neautralisation
- when an acid and an alkali react together, under standard conditions, to form 1 mole of water
- enthalpy change
