Question

Using the data (all values are in kcal mol⁻¹ at 25ºC) given below, calculate the bond energy of C–C and C–H bonds.
$\Delta H^0_{combustion}$(ethane) = –372.0
$\Delta H^0_{combustion}$(propane) = –530.0
$\Delta H^0_{C(s) \rightarrow C(g)}$ = 172.0
Bond energy of H–H = 104.0
$\Delta H^0_f$ of H₂O(l) = –68.0
$\Delta H^0_f$ of CO₂(g) = –94.0
