Practice: Consider the following equation:
Determine the bond enthalpy value for the F–S bond.
Bond Energy is the amount of energy stored within a chemical bond.
Bond Energy
Concept #1: Bond Energy
When individual bond energies are given, we will use the first formula.
Example #1: Calculate the ∆Horxn if the bond enthalpies of NΞN, H–H and N–H are 945 kJ/mol, 432 kJ/mol and 391 kJ/mol respectively.
Practice: Use the bond energies to estimate the enthalpy of reaction for the combustion of 5 moles of acetylene:
