A process at constant T and P can be described as spontaneous if
ΔG < 0 and nonspontaneous if ΔG > 0. Over what range of
temperatures is the following process spontaneous? Assume that
gases are at a pressure of 1 atm. (Hint: Use the data below to
calculate ΔH and ΔS [assumed independent of temperature and equal
to ΔH° and ΔS°, respectively] and then use the definition of
ΔG.)
