Edexcel IAL Chemistry AS 6.10 Deriving mean bond enthalpy
Edexcel IAL Chemistry AS 6.10 Deriving mean bond enthalpy
List bonds broken and formed with stoichiometric counts, substitute them into ΔH=broken−formed and isolate the unknown before dividing by its bond multiplicity.
How this is tested
- Count reactant and product bonds using molecular structures and equation coefficients.
- Rearrange bonds broken minus bonds formed to calculate an unknown bond enthalpy.
