|AP Chemistry - Bond Energies Worksheet|
|1.||Define bond energy
and atomization energy. What is bond dissociation energy?
|2.||Use a standard bond
energy table to compute the approximate atomization energy of NH3.
much energy would be released during the formation of the bonds in one mole
of acetone molecules? Acetone, the solvent usually found in nail polish
remover, has the structural formula:
|4.||The standard heat
of formation of ethanol vapour, C2H5OH(g) is
DHfo=-235.3 kJ/mol. Use the bond energy table
to estimate the C-O bond energy in this molecule.
The structure of the molecule is
|5.||What would be the
approximate heat of formation of CCl4 vapour at 25oC
and 1 atm?
|6.||Which substance should
have the more exothermic heat of formation, CF4 or CCl4?
