The enthalpy change in a reaction is given by-
ΔH°rxn = ∑nΔH°f,products - ∑nΔH°f,reactants
This can be expressed in terms of bond energy as-
ΔH°rxn = BEreactants - BEproducts
Therefore, the calculated bond energy according to the above equation will be-
ΔH°rxn = [ (C-C) + 2(C-O) + 4(C-H) + 2(O-H) ] - [ (C-C) + 2(C-O) + 4(C-H) + 2(O-H) = 0 kJ/mol
<h3>What is enthalpy change?</h3>
Enthalpy change is a measure of the energy emitted or consumed in a reaction. This can be determined using the following equation which involves standard enthalpy of reactant and product formation:
ΔH°rxn = ∑nΔH°f,products - ∑nΔH°f,reactants
<h3>What is bond energy?</h3>
Bond energy is defined as the amount of energy needed to dissociate a mole of molecules into their individual atoms.
