We’re being asked to determine the equilibrium constant (K) at 298 K for the given reaction:
C6F6(g) ↔ 3C2F2(g)
Recall that ΔG˚rxn and K are related to each other:
We can use the following equation to solve for ΔG˚rxn:
Given that the ∆G°f (kJ/mol) at 298 K for difluoroacetylene (C2F2) and hexafluorobenzene (C6F6) are 185.3 and 81.3, respectively, what is K at 298 K for the reaction, C6F6(g) ↔ 3C2F2(g)?
