28 Ιουλ 2022 · A negative change indicates the reaction is exothermic, while a positive value means it is endothermic. This tool calculates the change of the reaction in two ways: 1. Using the enthalpy equation, or 2. Using the standard enthalpies of formation of the components from a reaction scheme.
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 ...
