From the data in Appendix G, we have:
S(s) → S(g) ΔH°f = 223 kJ/mol
C(s) → C(g) ΔH°f = 715 kJ/mol
CS2(l) → CS2(g) ΔH°f = 88 kJ/mol
To calculate the ΔH°rxn using bond energies, we’re going to use the following equation:
Using the standard enthalpy of formation data in Appendix G, calculate the bond energy of the carbon-sulfur double bond in CS2.
