Worksheet: Bond Energy
In this worksheet, we will practice using net changes in bond energy during reactions to calculate the bond energies of reactants and products.
Ethene and iodine react to form 1,2-diiodoethane. The equation for this reaction is shown.
The total energy change per mole of ethene reacted is kJ/mol. The energies of selected bonds in the reactants and products are given in the table.
Calculate, to the nearest kilojoule per mole, the bond energy of the bond.
