Energy Changes in Reactions · Thermodynamics

Bond Energy Calculations

Using mean bond enthalpies to calculate the overall energy change of a reaction.

Key Questions

  1. 1How is the net energy change of a reaction related to the strength of the bonds broken and formed?
  2. 2Why is bond breaking considered an endothermic process?
  3. 3How accurate are theoretical bond energy calculations compared to experimental calorimetry?
