C2H4(g) + H2O(g) ⟶ C2H5OH(l)
ΔH°C2H5OH = -227.7 kJ/mol
ΔH°C2H4 = +52.4 kJ/mol
ΔH°H2O = -241.82 kJ/mol
Ethylene, C2H2, a byproduct from the fractional distillation of petroleum, is fourth among the 50 chemical compounds produced commercially in the largest quantities. About 80% of synthetic ethanol is manufactured from ethylene by its reaction with water in the presence of a suitable catalyst. C2H4(g) + H2O(g) ⟶ C2H5OH(l)
Using the data in the table in Appendix G, calculate ΔH° for the reaction.
