18 kJ/mol indicate the endothermic nature of the adsorption process, and a decrease of Gibb's free energy (DG) with increasing temperature indicates the spontaneous nature of the adsorption process.
Once the molecules were optimised at the PM3 semi-empirical model and no imaginary frequencies were found, the thermodynamics - entropy, enthalpy, heat of formation, electric charge distribution and vibrational transitions, the Gibb's free energy and the equilibrium constants were evaluated [16].
The change of Gibb's free energy is negative for o-6 and m-7, indicating the process of formation from3-(benzyloxy)-N-[2-(2-methoxyaniline)-2-oxoethyl]-4- methyl-2-nitrobenzamide at room temperature is spontaneous.
