Energy per mol

Application of this equation to acid/base reaction (4-5) leads to a net change in Gibbs energy per mol as shown in Eq. (4-8), if only pure electrostatic interactions are considered [8]. 

At 250° C. this reaction occurs with the liberation of almost 20,000 calories of energy per mol. In the presence of active catalysts especially, this decomposition of carbon monoxide to form carbon dioxide and a highly reactive carbon, complicates any attempt to use it as an oxygenating agent in vapor phase reactions. Consequently, very little experimentation has been done with the direct object of reacting hydrocarbons with carbon monoxide to form oxygen containing compounds. 

This expression gives the lattice energy per moL N is Avogadro s number. The factor I compensates for double counting in the summation, k represents the number of ions in the unit cell, / the unit cells. For a lattice with one kind of cation or anion q.(4.5) can be rewritten as ... 

In this view, T has the dimension of energy per mol. We could readily measure the temperature in terms of volume and pressure - if an ideal gas is available. So we have traced back the temperature to the (mean) energy of a particle. The temperature is expressed in terms of mechanical quantities.

If two phases (1 and 2) of a pure substance are in equilibrium (gas-liquid, gas-solid, liquid-liquid, liquid-solid, or solid-solid) at Tj and Pi, then the Gibbs energy per mol (or per Ibm or kg) must be the same in each of the equilibrium phases. 

Example 6.6 For liquid mixtures of a and /3 (two imaginary chemicals) at some fixed T and P the Gibbs energy per mol of the mixture is given by... 

Does this mean that the Gibbs energies per mol of the two phases must necessarily be equal, Or are these quanti-... 

Assuming that -pentane and -hexane form an ideal solution, sketch plots of / -Xpentane> volume per mol-Xpentane, enthalpy per mol-Xpentane, entropy per mol-Xpentane, and Gibbs energy per mol-Xpentane for liquid mixtures of -pentane and -hexane at 25 °C (see Table 7.F). Simple sketches with a few numerical values will be satisfactory. 

The partial molar free energy per mol of monomer, AG 1 and per base mol of polymer, AG2 are then functions of composition and may be evaluated from an appropriate equation for mixing of monomer and polymer, e.g., the Flory-Huggins equation. For a monomer dissolved in a solvent the situation is more complex and the ceiling temperature at a given monomer concentration (or the equilibrium concentration of monomer at a given temperature) is dependent on the nature of the solvent and the composition of the medium (Refs. 28,29,112,113,114,160). For the case where both monomer and polymer are in...
