Ionization enthalpy can be defined as the minimum amount of energy required to remove an electron from the valence shell of an isolated gaseous atom in its ground state resulting in the formation of a positive ion. It is basically the quantitative measur...
Hence, the large enthalpy cost of moving to ES’ is balanced with the entropy gain at precisely around 25 °C, where −TΔSeq = −32 kcal mol−1. At lower temperatures, the system will primarily reside in ES and is higher in ES’. The magnitudes of ΔHeq and Δ...
