Homework Help: Gibbs Free Energy of Atomic Hydrogen Ionization

  1. May 3, 2012 #1
    1. The problem statement, all variables and given/known data
    Despite extensive searches of the web and my old honors freshman chem text, I have yet to find a kj /mol value for either the standard Gibbs' Free Energy (Delta-G-naught (298° K)) or standard ENTROPY (Delta-S-naught) for the ionization of gaseous ATOMIC Hydrogen (or for the reverse process; gaseous atomic Hydrogen formation from free protons and electrons)

    Thanks in Advance

    2. Relevant equations

    3. The attempt at a solution
    I can readily find reference to the 1312 kj/mol Ionization "Energy" (ENTHALPY (Delta-H-naught)) but I need the Gibbs free energy for comparisons, or at least the standard entropy change from which I can calculate Delta-G-naught
