In this chemistry tutorial video, I first go through what a bond energy or bond enthalpy is and two factors that affect bond length and strength, and thus bond energy: bond order (type of bond like single vs. double vs triple) and radius. We recall that a longer bond is a weaker bond, and a shorter bond is a stronger bond, and we relate this to ...

This video covers how to calculate ΔH using average bond enthalpies.

If you know the energy required to break all the bonds in the reactants AND make all the bonds in the products you can work out the overall energy change for the reaction. Assume STP and this only works if everything involved is a gas. (Else the energy you put in may cause evaporation, boiling, hydrogen-bond breaking etc).

3.1.4.4 Bond enthalpies Mean bond enthalpy. Students should be able to: •• define the term mean bond enthalpy •• use mean bond enthalpies to calculate an approximate value of ΔH for reactions in the gaseous phase •• explain why values from mean bond enthalpy calculations differ from those determined using Hess’s law.
