Calculate the enthaply change for the process :
`C Cl_4`(g) `to` `C`(g)+`4Cl(g)` and calculate the bond enthalpy of `C-Cl` in `C Cl_4(g)`
`triangle(vap))H^(@) (C Cl_4`)= 30.5 kJ `mol^-1`
`trianglef H^(@)(C Cl_4)` = 135.5 kJ `mol^-1`
`triangle_a H^@(C) = 715.0 kJ` `mol^-1`
`triangle_a H^@(Cl_2)(`atomisation`) = 242 kJ mol^-1`
