Gibbs fiee energy

Let 1 — q be die number of moles of A, and consequently 2q be the number of moles B, and 1 -I- the total number of moles. Since q determines the composition of the system, is a unique and, in principle, known function of q, qMix w q). In Section in,A, we showed that, in the absence of chemical reactions, statements about the Gibbs free energy are only significant to within a term which is linear in the composition. This is not true when chemical reactions can take place, because, for instance in the case at hand, the pure component Gibbs fiee energy of component B is given by...

The Gibbs equations derived for fiee, S/L, and S/G interfaces provide a uniform picture of physical adsorption however, they eannot give information on the structure of energy [i.e., we do not know how many and what kind of physieal parameters or quantities influenee the energy (heat) processes connected with the adsorption]. As it is well known these heat proeesses ean be exactly measured in a thermostat of approximately infinite eapacity. This thermostat eontains the adsorbate and the adsorptive, both in a state of equilibrium. We take only the isotherm proeesses into account [i.e., those in whieh the heat released during the adsorption process is absorbed by the thermostat at eonstant temperature dT = 0) or, by eonverse processes (desorption), the heat is transferred fi om the thermostat to the adsorbate, also at eonstant temperature]. Under these conditions, let <7n -mol adsorptive be adsorbed by the adsorbent and, during this process, an...
