Molar reaction entropy generated

We have taken over this name for lack of a better one in order to distinguish between the effects caused by differences of entropy demands and those caused by entropy generation. In Eq. (8.25), the expression on the left represents the latent molar reaction entropy and the one on the right, the generated molar reaction... 

Here the notation N has been used to indicate all the mole numbers N = (jV, Ni,..., A c), and we have written these equations in terms of total thermodynamic properties rather than molar or specific properties since, as a result of the chemical reaction, there is a change in the number of moles of each species. Also, as before, we assume that the entropy generation term is zero, thereby obtaining an upper bound on the energy released in an explosion. 

Let us consider the generation of long chains of a statistical binary copolymer at low conversions. The reaction of the active centre with the monomer exhibits the characteristic molar heat of reaction H and molar entropy change S... 

The molar volume change in ionization reactions at higher temperatures and pressures cannot be calculated for most of the aqueous complexes because of a lack of data on isobaric expansion and isothermal compressibility coefficients. Entropy and heat capacity correlations have recently been used to generate equation of state parameters for estimating molal volumes of aqueous complexes at elevated temperatures and pressures (Sverjensky, 12). These coefficients are available for aqueous complexes only of univalent anions and, therefore, the pressure dependence of ionization constants at elevated temperatures cannot be estimated using Equation 4. 

Several points follow. The reaction under consideration is exothermic becanse the molar enthalpy of A exceeds that of B the A population loses heat-generating potential, so to speak, when members convert to B. In turn, the greatest entropy change for the heat bath would occur if all the A converted to B. The mixing ensures otherwise, however, by the maximum of at x=0.500 moles. The latter...
