    Sorry, for part three, it is not only because of 3/2 moles from O2(g). Part 3 is asking for "equilibrium pressure of O2(g) over M(s) at 298K? (atm)." Although it is 3/2 nevertheless, because M(s) also has 1 mole, it is due to O2(g)/M(s) so (3/2)/(1) =3/2.

    I see what asker did wrong too, because she left it incomplete at first. Since Kelsey found #1, 10.6, I'll leave it at that. Part 2: (Gibbs energy)= -RTln(K) -> 10.6 kJ/mol= -(8.314 J/molxK)(298K)ln(K) -> 10.6 x 10^3 (J/mol) = -(2477.6 J/mol)ln(K) ->
