Textbook Question

Chapter 7.19B, Problem 7.36P

The dehydrogenation of butane to trans-but-2-ene has ΔH° = +116kJ/mol( +27.6kcal/mol) and ΔS° = + 117J/Kelvin - mol (+28.0cal/Kelvin — mol).

a. Compute the value of ΔG° for dehydrogenation at room temperature (25 °C or 298 °K). Is dehydrogenation favored or disfavored?
b. Compute the value of ΔG for dehydrogenation at 1000 °C, assuming that ΔS and ΔH are constant. Is dehydrogenation favored or disfavored?
