21. :Thermodynamics is a significantly broader field than just entropy and enthalpy . 22. Enthalpy does obey the laws of conservation; unless you ignore work.23. Often the whole enthalpy is carried by entropy and thus measurable calorimetrically. 24. The enthalpy of adsorption can determined from constant pressure calorimetry: 25. Such an approach was used to revise primary alkylamine enthalpies of formation. 26. Nowadays the enthalpy values of important substances can be obtained using commercial software. 27. Chemists may use standard enthalpies of formation for a reaction that is hypothetical. 28. The specific enthalpies are indicated in kJ / kg. 29. Union enthalpy and enthropy from the latter correspond to high-affinity ligands. 30. The enthalpy of solution is most often expressed in mol at constant temperature.
