question

Use the following table to calculate the enthalpy of propane at 25° C and at oneatmassuming the enthalpy of solid carbon and hydrogen gas to be zero at that temperature and pressure. Bond Energy Bond Energy H - H 104.2 H - l 71.4 C - C 83.1 C - N 69.7 Cl -Cl 58.0 C - O 84.0 Br - Br 46.1 C -Cl 78.5 I - I 36.1 C - Br 65.9 C - H 98.8 C - I 57.4 N - H 93.4 O - O 33.2 O - H 110.6 N \equiv N 226 H -Cl 103.2 C = C 147 H - Br 87.5 C \equiv C 194 C = O 164 in formaldehyde 171 in otheraldehydes 174 inketones, Resonance energy in kcal/g mole Benzene ring = 37 Naphthalene= 75 Carboxylic acids = 28 Esters= 24 The heat of vaporization for carbon(s) to carbon(g) = 171.70 kcal/mole.
