What is Mean Bond Enthalpy and How Do I Use It?

WebThe Bond Enthalpy is the energy required to break a chemical bond. It is usually expressed in units of kJ mol -1, measured at 298 K. The exact bond enthalpy of a particular chemical bond depends upon the molecular environment in which the bond exists. Therefore, bond enthalpy values given in chemical data books are averaged values. http://www.kentchemistry.com/links/Kinetics/BondEnergy.htm
