11. Given the following average bond energies in kJ/mol?
DeltaHBE: C-H = 412; C-I = 228; H-I = 299,
and the enthalpy of vapourisation of iodoethane is 32.0 kJmoll and the enthalpy of
atomisation of iodine is 107 kJmol'', calculate the enthalpy change for the reaction
C2H6(g) + I2(s) ====> C2H5I(1) + HI(g)
