Example using enthalpy of combustion and formation Construct an enthalpy cycle and calculate the value of Hf (C2 H5OH(l)) given the following data:
Determine enthalpy change for SO2 (g) + 2H2S (g) --> 2H2O (l) + 3S (s) • Use the following values (all in kJ) • Standard enthalpy of formation • H2O(l): - 286 • H2S(g): - 20.2 • Standard enthalpy of combustion of S (monoclinic) = - 297.2kJ • Add equations and draw an enthalpy cycle.
