Interpretation:
Reason for why glucose has a lower specific enthalpy than the lipid decanoic acid even though these compounds have similar molecular masses should be justified using the given bond enthalpies values.
Concept Introduction:
Bond enthalpy:
The measure of stability of molecule is bond enthalpy. The change in enthalpy is related in breaking a specific bond of 1 mole of gaseous molecule. In solids and liquids bond enthalpies are affected by neighboring molecules. There is possibility to predict the enthalpy of reaction using the average bond enthalpies. Energy is always needed for the breaking of
The enthalpy of reaction in gas phase is given by,
