Ethylene glycol, HOCH2CH2OH, is used as antifreeze. It is produced from ethylene oxide, C2H4O, by the following reaction.
C2H4O(g) + H2O(l) ? HOCH2CH2OH(l)
Use Hess's law to obtain the enthalpy change for this reaction from the following enthalpy changes.
2 C2H4O(g) + 5 O2(g) ? 4 CO2(g) + 4 H2O(l) ?H = -2612.2 kJ
HOCH2CH2OH(l) + 5/2 O2(g) ? 2 CO2(g) + 3 H2O(l) ?H = -1189.8 kJ
