We observe that the terms involving T2 are variable, but that those involving Ti are not, because for the integration of Eq. 12.28 we almost always take Ti as the temperature of the Gibbs energy tables, normally (but not always) 298.15 K. Thus, we rewrite this as... 

Table 2.10 shows the effect of substituents on the endo-exo ratio. Under homogeneous conditions there is hardly any substituent effect on the selectivity. Consequently the substituents must have equal effects on the Gibbs energies of the endo and the exo activated complex. 

Table 6.1 Enthalpies and Gibbs Energies of Formation, Entropies, and Heat...

The tables in this section contain values of the enthalpy and Gibbs energy of formation, entropy, and heat capacity at 298.15 K (25°C). No values are given in these tables for metal alloys or other solid solutions, for fused salts, or for substances of undefined chemical composition.
