The standard enthalpy of formation (\( \Delta H_f^\circ \)) is the change in enthalpy when one mole of a compound is formed from its elements in their standard states. Here are the values for the compounds you're interested in:
-
Water (H₂O): The standard enthalpy of formation for liquid water is approximately \( -285.83 , \text{kJ/mol} \).
-
Sodium Hydroxide (NaOH): The standard enthalpy of formation for solid sodium hydroxide is approximately \( -425.83 , \text{kJ/mol} \).
Please note that these values can vary slightly depending on the source, but these are widely accepted standard values.
