Part A: For which of the following reactions is Î”Hâˆ˜rxn equal toÎ”Hâˆ˜f of the product(s)? You do not need to look up any values toanswer this question.
2Li(s)+F2(g)â†’2LiF(s)
S(s)+O2(g)â†’SO2(g)
Li(s)+12F2(g)â†’LiF(s)
SO(g)+12O2(g)â†’SO2(g)
SO3(g)â†’12O2(g)+SO2(g)
Li(s)+12F2(l)â†’LiF(s)
Part B: The combustion of propane, C3H8, occurs via thereaction
C3H8(g)+5O2(g)â†’3CO2(g)+4H2O(g)
with heat of formation values given by the following table:
Substance Î”Hâˆ˜f
(kJ/mol)
C3H8 (g) -104.7
CO2(g) âˆ’393.5
H2O(g) âˆ’241.8
Calculate the enthalpy for the combustion of 1 mole ofpropane.
