At high temperatures, some unusual sodium oxides, Na2O, Na2O2 and NaO2 form. The equilibrium constants for the dissociation reactions of these oxides are listed below. 1 K = 2 x 10-25 2 1) Na20(s) = 2 Na(2) + 3 026) 2020) 2) Naog) = Na(2) + K = 2 x 10-5 2 K = 5 x 10-29 3) Na 02(s) = 2 Na(2) + O2(g) 4) Naoz(s) = Na(2) + 029) K = 3 x 10-14 Use the information above to predict the equilibrium constant for the reaction below. 2NaO(g) = Na 202(s) K = ? Enter your answer using scientific notation. Round the answer to one significant figure. For example 6.5 x 10^-10 should be entered as 6E-10.
