The bond energies of `C=C` and `C-C` at `298 K` are `590` and `331 kJ mol^(-1)`, respectively. The enthalpy of polymerisation per mole of ethaylene is

The polymerisation of ethylene to linear polyethylene is represented by the reaction nCH_(2)=CH_(2)rarr(-CH_(2)-CH_(2)-)_(n) When n has a large integral value. Given theat the average enthalpies of bond dissociation for C=C and C-C at 298K are +590 and +331kJ mol^(-1) respectively, calculate the enthalpy of polymerisation per mole of ethylene at 298K .
