Sep 5, 2016 · The E 0 value is standard electrode potential which depends on ionization energy. Since, Mn +2 ion gets a d 5 configuration which is half filled and hence third ionization energy becomes much higher for the cation and it becomes more stable so it gets a higher positive E 0 value, while the Cr +2 ion gets a d 4 configuration and so it has less E ...

The E 0 value is standard electrode potential which depends on ionization energy. Since, Mn +2 ion gets a d 5 configuration which is half filled and hence third ionization nergy becomes much higher for the cation and it becoems more stable so it gets a higher positive E 0 value, while the Cr +2 ion gets a d 4 configuration and so it has less E 0 value.

TheE θ (M 2+ /M) value of a metal depends on the energy changes involved in the following: 1. Sublimation: The energy required for converting one mole of an atom from the solid state to the gaseous state. 2. Ionization: The energy required to take out electrons from one mole of atoms in the gaseous state. 3.

Nov 10, 2014 · because the enthalpy of hydration of cu is less than enthalpy of atomisation+enthalpy of ionisation .therfore net energy/enthalpy= -Δhyd + ( Δ at H o +ΔiH o)=a +ve value...therefore reduction pottential value of cu is +ve.
