Calculate the enthalpy of polymerization of ethylene from the following data: Ethylene, C2H4(g) polymerizes to form polyethylene, (C2H4)n(s) with ΔHrxn = -44.0 kJ/mol at 298 K. Additionally, it is known that the standard enthalpies of formation of C2H4(g) and polyethylene (C2H4)n(s) are 52.3 kJ/mol and -128.2 kJ/mol, respectively. Assuming the enthalpy of polymerization is independent of temperature, calculate ΔHºp for the reaction.
