Ethanol, C2H5OH, is made industrially by the reaction of water with ethylene, C2H4.
Determine the enthalpy change for the reaction: (4 marks) C2H4(g) + H2O(l) C2H5OH(l)
given the following thermochemical equations:
(1) C2H4 (g) + 3O2(g) → 2CO2(g) + 2H2O(l) ΔrH = - 1411.1 kJ
(2) C2H5OH(l) +3O2(g) → 2CO2(g) + 3H2O(l) ΔrH = - 1367.1 kJ
