The standard enthalpy of LiF formation is evaluated to be equal -- plus or minus kcal/ mole. (R.V.J.). heat according to equation (6) for steel A is shown. Excellent agreement was obtained in whole investigated temperature range.

Fig. Comparison of experimental and calculated specific heat of steel A (a), enthalpy of steel A (b) The results for steel B are presented in fig. At low temperature region good agreement was obtained with.

Mathematically, we can think of the enthalpy of reaction as the difference between the potential energy from the product bonds and the potential energy of the reactant bonds.

But we know that enthalpy of a reaction depends on the temperature according to Kirchoff's equations. So does this mean that bond energies also change with temperature.
