21 Αυγ 2024 · You can calculate the enthalpy change in a basic way using the enthalpy of products and reactants: ΔH° = ∑ΔH products − ΔH reactants. For example, let's look at the reaction Na + + Cl-→ NaCl. To find enthalpy change: Use the enthalpy of product NaCl (-411.15 kJ). Find the enthalpy of Na + (-240.12 kJ) and Cl-(-167.16 kJ). Calculate ...
28 Ιουλ 2022 · For a reaction, the enthalpy change formula is: ΔH° reaction = ∑ΔH° f (products) - ∑ΔH° f (reactants) where: ΔH° reaction — Standard enthalpy change of formation expressed in kJ; ∑ΔH° f (products) — Sum of the standard enthalpies of formation of the products multiplied by their corresponding numbers of moles, expressed in kJ ...
