WebJan 15, 2024 · Electron Affinities. Exothermic vs endothermic process; Periodic Trend; References; Outside Links; Example of IE 1 of Magnesium: Mg(g) -> Mg + (g) + e-I 1 = 738 kJ/mol. IE 1 stands for the first ionization energy: the energy the atom requires to expel the first electron from its orbital. Similarly, the second ionization energy, will be the energy … WebJan 30, 2024 · This relationship can help to determine whether a reaction is endothermic or exothermic. At constant pressure, an endothermic reaction is when heat is absorbed. This means that the system consumes heat from the surroundings, so \(q\) is greater than zero. Therefore according to the second equation, the \(\Delta{H}\) will also be greater than zero.
