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:

$\dfrac{kJ}{mol}$
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:

$\Delta_{r} H^\ominus = \sum_{i} \nu_{prod., i} \Delta_{cr} H^\ominus_{prod., i} - \sum_{i} \nu_{subst., i} \Delta_{cr} H^\ominus_{subst., i}$
where:
- $\Delta_{r} H^\ominus$ - standard enthalpy of chemical reaction,
- $\nu_{prod., i}$ - the stoichiometric factor of the i-th product resulting from the chemical reaction equation,
- $\nu_{subst., i}$ - the stoichiometric coefficient of the i-th substrate resulting from the chemical reaction equation,
- $\Delta_{cr} H^\ominus_{prod., i}$ - standard enthalpy of creation of i-th product,
- $\Delta_{cr} H^\ominus_{subst., i}$ - standard enthalpy of creation of i-th substrate.
