Some facts

  • The standard enthalpy of creation is the enthalpy of substance creation from elements under standard conditions i.e. at a pressure of 1013,25 hPa and a temperature of 25 °C.
  • We conventionally assume, that enthalpy of creation of chemical elements is equal to zero.
  • Enthalpy of creation is ussualy given in kilojoules per mole:
    kJmol\frac{kJ}{mol}

  • The standard enthalpy of creation is specific for a given substance.
  • Basing on the enthalpy of creation for all products and substrates, we can determine the enthalpy of the chemical reaction:
    ΔrH=iνprod.,iΔcrHprod.,iiνsubst.,iΔcrHsubst.,i\Delta_{r} H^\ominus = \sum_{i} \nu_{prod., i} \Delta_{cr} H^\ominus_{prod., i} - \sum_{i} \nu_{subst., i} \Delta_{cr} H^\ominus_{subst., i}
    where:
    • ΔrH\Delta_{r} H^\ominus - standard enthalpy of chemical reaction,
    • νprod.,i\nu_{prod., i} - the stoichiometric factor of the i-th product resulting from the chemical reaction equation,
    • νsubst.,i\nu_{subst., i} - the stoichiometric coefficient of the i-th substrate resulting from the chemical reaction equation,
    • ΔcrHprod.,i\Delta_{cr} H^\ominus_{prod., i} - standard enthalpy of creation of i-th product,
    • ΔcrHsubst.,i\Delta_{cr} H^\ominus_{subst., i} - standard enthalpy of creation of i-th substrate.
