WebAug 2, 2024 · To understand standard enthalpy of formation of O2 Equal to Zero, you need to understand the definition of standard enthalpy of formation. This is the change of enthalpy when one mole of a substance in its standard state is formed from its elements under standard state conditions of 1 atmosphere pressure and 298K temperature. WebBut you should, of course, know how to calculate this from enthalpy changes of formation. ΔH° = -890.4 kJ mol -1. So if you had to calculate the Gibbs free energy change at, say, 298 K, you can just slot the numbers in: ΔG° = ΔH° - TΔS°. ΔG° = -890.4 - 298 (-0.2442) = -817.6 kJ mol -1. It is easy as long as you remember to convert the ... t-shirt chat
