Calculating the Gibbs Free Energy Change I - Video Solution

Calculate the standard Gibbs free energy change (ΔG˚) at 25˚C for the reaction below.
2 W(s) + 3 O2(g) ≡ 2 WO3(s)   ΔH˚=-1686 kJ

At 25˚C, is this reaction spontaneous or nonspontaneous?

At what temperature will this reaction change in spontaneity?
