Draw the Bom-Haber cycle for the formation of MgO (as shown for CsF on p. 503 of the textbook). Use the following energies to make your diagram. Your diagram does not have to be to scale. Energy to vaporize one mole of Mg(s) = +148 kJ Energy to dissociate one mole of O(g) = + 249 kJ First ionization energy of one mole of Mg(g) = +738 kJ Second ionization energy of one mole of Mg(g) = +1451 kJ First electron affinity of one mole of O(g) = -141 kJ Second electron affinity of one mole of O(g) = +798 kJ Lattice energy of one mole of MgO(s) = -3845 kJ How much energy is released by the reaction Mg(s) + 1/2O(g) MgO(s) Why must you apply heat to the reactants to get them to react if heat is released by the reaction overall?
