For each of the following reactions, calculate ΔH∘rxn,
ΔS∘rxn, and ΔG∘rxn at 25 ∘C. State whether or not
the reaction is spontaneous. If the reaction is not spontaneous,
would a change in temperature make it spontaneous? If so, should
the temperature be raised or lowered from 25
∘C?2CH4(g)→C2H6(g)+H2(g), Calculate ΔS∘rxn at 25 ∘C.
2NH3(g)→N2H4(g)+H2(g) Calculate ΔS∘rxn at 25 ∘C.
N2(g)+O2(g)→2NO(g) Calculate ΔS∘rxn at 25 ∘C.
2KClO3(s)→2KCl(s)+3O2(g) Calculate ΔS∘rxn at 25 ∘C.
