If the bond energies of C=C and C-C at 298 K are 590 and 331 kj mol-1 respectively then enthalpy of polymerization per mole of ethylene is.
Polymerization reaction occurs as nCH2= CH2→ (-CH2-CH2—)n, One mole of C = C bond is broken and two moles of C—C bonds are formed per mole of ethylene. ∆H=59G—2 ×331 = 590 - 662 = -72 kj per mole of ethylene
