We are being asked to determine the value of ΔG°_{f} for SF_{4}(g) given the reaction

SF_{4} (g) + F_{2} (g) → SF_{6} (g)

with the value of ΔG° equal to -374 kJ

Recall the equation for **ΔG˚***_{rxn}*:

$\overline{){\mathbf{\u2206}}{\mathbf{G}}{{\mathbf{\xb0}}}_{{\mathbf{rxn}}}{\mathbf{}}{\mathbf{=}}{\mathbf{\u2206}}{{\mathbf{G}}}_{\mathbf{f}\mathbf{,}\mathbf{}\mathbf{prod}}{\mathbf{}}{\mathbf{-}}{\mathbf{}}{\mathbf{\u2206}}{{\mathbf{G}}}_{\mathbf{f}\mathbf{,}\mathbf{}\mathbf{react}}}$

For the reaction

SF_{4} (g) + F_{2} (g) → SF_{6} (g)

the value of ΔG° is -374 kJ. Use this value and data from Appendix 4 to calculate the value of ΔG°_{f} for SF_{4}(g).
