Enthalpy of formation from a reaction.This form will calculate the enthalpy of formation of a species using ab initio results and experimental enthalpies of formation. Fill in the blanks with the appropriate information from your calculations. To clear the input boxes press the clear button at the bottom of the form. The descriptor is used for you to identify the species. It is not used in the calculations. The count is the quantity of a given species. Use it to balance the reaction. The electronic energies are from your ab initio calculation.
The value in the experimental row for reactant 1 is the predicted enthalpy of formation using the calculated values entered for all species and the experimental values for the other species.
