Question

If ionization energy of F anion is 320 Kj/mol .The electron gain enthalpy of flourine would be....plz solve or give a hint get a neww follower

Answer 1

the hint is distance ×displacement

Answer 2

The Electronegativity according to the Mullikan's scale is given by the formula

Electronegativity = (Ionisation Energy + Electron Affinity)/540

if Ionisation Energy & Electron Affinity(Electron Gain Enthalpy) are in KJ/mol

 

Electronegativity = (Ionisation Energy + Electron Affinity)/5.6

if Ionisation Energy & Electron Affinity(Electron Gain Enthalpy) are in Electron Volts(eV)

When we use the Ionisation Energy & Electron affinity measured in Electron Volts(eV) the Mullikan's electronegativity values are found to be 2.8 times higher than the pauling values so in order to get the mullikan's scale from the pauling's scale simply multiply the pauling scale values by 2.8 & remember that the Ionisation Energy & Electron Affinity values must be given in electron volts(eV)

Hope this helped you immensely..!
