Helmholtz relationship

We use the Gibbs-Helmholtz relationship to obtain the derivatives on the left... 

When an adsorbing surface is exposed to a gas or vapour adsorption will take place, being accompanied by the absorption or evolution of heat. Such thermal changes have already been noted in the extension and contraction of surface films of liquids. Although the direct determination of the surface energy of solid surfaces presents many experimental difficulties yet of its existence there is no doubt. On the adsorption of a gas or vapour a diminution in the free surface energy of the system likewise occurs. From the Gibbs-Helmholtz relationship dcr... 

According to Gibbs-Helmholtz relationship, the Helmholtz energy of mixing of system can be obtained by integrating the internal energy... 

By analogy with free energy, the solvation enthalpy can be represented by the addition of the corresponding enthalpy components, as noted in Eq. 4-9, where each term might be determined a priori by using the Gibbs-Helmholtz relationship (Eq. 4-3) ... 

For the HPLC separation of low molecular weight organic compounds and various biomacromolecules, the near-equilibrium criterion has generally been assumed for the binding and desorption behaviour. Changes in thermodynamic parameters due to polypeptide- or protein-ligate interaction can thus be depicted in terms of the Gibbs-Helmholtz relationship, namely,... 

Finally, once G° (0) is aveiUable as a function of temperature, and S° can be immediately obtained using the appropriate Gibbs-Helmholtz relationships S =... 

If the standard potential of an electrode is known at two or more temperatures, the entropy of the reversible ion can be determined by using a form of the Gibbs-Helmholtz relationship. As seen in 331 the standard entropy change may be expressed in terms of the standard electrode potential, viz.,... 

In the RPC and HlC of peptides and proteins, the near-equilibrium eondition has generally been assumed for binding and desorption. Changes in the thermo-dynamie parameters of the ligand-1 igate interaetion ean thus be depleted in terms of eriteria speeified by the Gibbs-Helmholtz relationship ... 

The Helmholtz relationship also considers the state of polarization for incident and emergent fluxes.
