This is the enthalpy change associated.........

Explanation:

This is the enthalpy change associated with the formation of 1 mole of water from its constituent elements in their standard states under standard conditions, i.e.

#H_2(g) + 1/2O_2(g) rarr H_2O(l)#

#DeltaH_"rxn"^@=DeltaH_f^@=-285.8*kJ*mol^-1#

Of course, this value must be measured.
