Bond Enthalpies (AQA A level Chemistry)

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.

How do you know whether something is a double bond or a triple bond or single

[@simonflynn4515]

You’re either told or you can work it out from dot and cross or similar
