Example 16.7b: Evaluation of \(ΔG°\) Change from \(ΔH°\) and \(ΔS°\)

Use standard enthalpy and entropy data from Appendix G to calculate the standard free energy change for the reaction shown here (298 K). What does the computed value for \(ΔG°\) say about the spontaneity of this process?

\(\ce{C2H6(g)}\)\(\ce{->}\)\(\ce{H2(g)}\)\(\ce{ + }\)\(\ce{C2H4(g)}\)\(\ce{ }\)

Think about it...
