47PRACTICE PROBLEM
Use standard free energies of formation to calculate ΔG° at 25 °C for the following reaction:
S(g) + O2(g) → SO2(g)
How do the values of ΔG° calculated this way compare to those calculated from ΔH° and ΔS°? Which of the two methods could be used to determine how ΔG° varies with temperature?
