Question

how does enthalpy of atomisation affect the reduction potential of an element ?

Answer 1

Enthalpy of atomisation is the energy released during the formation of 1 mole of gaseous element from its elements.
Electrode potential value depends on the enthalpy of atomisation.
$$\begin{gathered} -nF{E}^0=∆H^0-T∆S^0 \\ {E}^0=-\left[\frac{∆H^0-T∆S^0}{nF}\right] \\ Moretheenthalpyofatomisationmorewillbetheredoxpotential.Thatmeans \\ theelementhavemoretendencytoundergoreduction. \end{gathered}$$
