Problem: Explain the difference between endothermic reactions and exothermic reactions with respect to the bond energies of the bonds broken and formed.

FREE Expert Solution

When talking about heat changes during a chemical reaction, reactions can be classified into two types:

  • Exothermic reaction: when heat is released as a result of reaction.
  • Endothermic reaction: when heat is absorbed as a result of reaction.


A chemical reaction is a process that involved breaking of old (reactant) bonds and formation of new (product) bonds.

The process of bond breaking is endothermic (ΔH=positive), while the process of bond formation is exothermic (ΔH=negative).
