Bond Dissociation Energy Suppose there is an element X which occurs naturally as X₂(g) X₂(g) + 20₂(g) → X₂04(9) X X₂04 has a structure '+ 0=-- AHOf of O(g) is 249 kJ/mol AHOf of X(g) is 460.5 kJ/mol AHºf of X₂04(g) is 15 kJ/mol The X-X single bond energy is 156 kJ/mol Use the above data to estimate the average X----O bond energ in X₂04. Give your answer to the nearest 1 kJ/mol.
