1. Estimate the enthalpy (kJ) from bond energies
CCl4(g) + O2(g) → CO2(g) +
2Cl2(g)
2. Estimate the enthalpy (kJ) from bond energies
H2(g) + CO2(g) → H2O(g) + CO(g)
3. Consider the condensation reaction of CCl4. Indicate ΔSo > 0, ΔSo ~ 0, or ΔSo < 0
4. Consider the following reaction: CaCO3(s) → CaO(s) + CO2(g), Indicate if ΔSo is >0, <0, or ~0
5. Consider the condensation reaction of CCl4 and select the accurate statement, (consider signs of ΔSo and ΔHo)
6. ΔH of the following reaction was estimated from bond energies and found to be -97 kJ.
N2(g) + 3H2(g) ---> 2NH3(g)
Fill in the blank with the correct statement: This reaction
_______

report on spontaneity)
a. is non-spontaneous at all temperatures
b. is spontaneous at all temperatures
c. can be spontaneous or non-spontaneous depending on
temperature.
