1.O2−(g)+e−→O3−(g)O^{2-}(g) + e^- \to O^{3-}(g)O2−(g)+e−→O3−(g); ΔHeg=744.7\Delta H_{eg} = 744.7ΔHeg=744.7 kJ/mole. The positive value of ΔHeg\Delta H_{eg}ΔHeg is due to:a.Energy is released to add 1 e−e^-e− to O2−O^{2-}O2−b.Energy is required to add 1 e−e^-e− to O2−O^{2-}O2−c.Energy is needed to add 1 e−e^-e− to O2−O^{2-}O2− to form O3−O^{3-}O3−d.None of the above is correctLogin to continueOnly logged in users canattempt or see the solution.
