A differential version of this statement can be obtained by taking the equality in the combined law of thermodynamics.
A differential version of this statement can be obtained by taking the equality in the combined law of thermodynamics. The Born-Haber technique assumes this physical rule to calculate lattice energies; other techniques pertinent to this law include calorimetric determination and determination of standard properties of formation. Also known as the law of constant heat summation, this law is concomitant with the fact that enthalpy is a state function. FTP, identify this law named after a German chemist which states that the enthalpy change in a chemical reaction is the same regardless of its path.
