The element oxygen was prepared by Joseph Priesley in 1774 by heating mercury(II) oxide. This is the reaction: HgO (s) = Hg(liquid) + 1/2O2(gas) From the information given of our book, determine the temperature at which the reaction will become spontaneous. See the section on Free Energy and spontaneity in our book. You will also find Appendix C very helpful as well. The delta H for the reaction is 90.84 kiloJoules/mol
a. 108 Kelvin
b. 430 Kelvin
c. 620 Kelvin
d. 775 Kelvin
