6.4 Bond Energy (Bond Dissociation Energy)& Enthalpy Changes (How to calculate enthalpy of water?)

In this lecture from Chapter 6: Chemical Energetics, I explain the concepts of Bond Dissociation Energy (Bond Energy) and Bond Enthalpy (Section 6.4 & 6.5). Learn how to define, understand, and calculate bond enthalpy of a reaction with clear examples. Ideal for Class 11 Chemistry (Punjab Board 2025 syllabus) students. ⸻ #ChemicalEnergetics #BondEnergy #BondEnthalpy #Class11Chemistry #ChemistryWithAAK #FirstYearChemistry #Thermochemistry #ChemistryLecture #PunjabBoard #ChemistryConcepts
