🤓 Based on our data, we think this question is relevant for Professor Nair's class at TAMU.
C6F6 (g) ⇌ 3 C2F2(g)
Step 1: We can use the following equation to solve for ΔH˚rxn:
ΔH˚rxn = 591100 J/mol
Step 2: We can use the following equation to solve for ΔG˚rxn:
ΔG˚rxn = 495400 J/mol
Step 3: Calculate for ΔS˚rxn.
The standard free energies of formation and the standard enthalpies of formation at 298 K for difluoroacetylene (C2F2) and hexafluorobenzene (C6F6) are
For the following reaction:
C 6F6 (g) ⇌ 3C 2F2 (g)
a. calculate ΔS° at 298 K.
