Difference Between Electron Affinity and Electron Gain Enthalpy

WebAnswer (1 of 2): Second electron affinity is always positive because this reaction will be endothermic. The first adding of electron makes the element anion and again if we are adding a electron to anion to overcome repulsion it is always positive. Web27 Oct 2015 · The 2nd electron affinity is defined as the enthalpy change for: X− (g) +e → X2− (g) Because the electron is negatively charged you can see that there will be repulsion between the ion and the electron making the process endothermic, hence the positive value. The reason why it can happen is that this is just one energy change in a whole ... ina burema
