Webb26 nov. 2024 · The standard molar enthalpy of formation ΔHof is the enthalpy change when 1 mole of a pure substance, or a 1 M solute concentration in a solution, is formed from its elements in their most stable states under standard state conditions. In this class, the standard state is 1 bar and 25°C. WebbThe definition of standard enthalpy of formation is the change in enthalpy when one mole of a substance is formed in its standard state from its constituent elements in their standard state at 298k and 1 atm. Since elements like Oxygen are in their standard state, there is no standard enthalpy of formation to talk about here. ( 24 votes)
