C6F6 (g) ⇌ 3 C2F2(g)

$\overline{){\mathbf{\Delta G}}{{\mathbf{°}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{\Delta H}}{{\mathbf{°}}}_{{\mathbf{rxn}}}{\mathbf{-}}{\mathbf{T\Delta S}}{{\mathbf{°}}}_{{\mathbf{rxn}}}}$

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 ###### Problem Details
