Energy conversion between kinds

Note that on the left-hand side of (2.3.15), we have the Gibbs energy of the one-component system characterized by T, P, Nt. On the right-hand side of (2.3.15), we have a different system. This is a system where the conversion between the two species L and H is frozen-in at the specific value of N (and = Nuj — N ). This is a different system since we do not allow the conversion between the two species. Nevertheless, the Gibbs energies of the two systems are equal (in the thermodynamic limit). We shall soon see that this kind of equality is not shared by all thermodynamic quantities of the system. 

The oldest example of the application of the transition state method is the reaction H + Hg = H2 + H and the similar reactions with deuterium. They have been measured partly directly, partly by the ortho-para-conversion. The calculation of the corresponding energy surface is the simplest example of its kind. Although in my opinion, the agreement between experiment and theory is not complete, the disagreement amounts to less than 50 per cent, with the most suitably chosen set of constants. A similar example is Cl -f- H2 = CIH H, where the agreement with the measurement of Rodebush is within... 

In order to avoid a social shock when the global energy system should transfer from fossil system to the CO2 recycling system using renewable energy, a hybridization between fossil and solar energy should be also discussed. That is, there are various kind of energy sources (solar, fossil fuels and their complex sources), and of carbon sources (CO2 from flue gas of combustion, CO2 from exhaust gas of fossil fuel chemical conversion, and carbon of fossil fuel itself).
