Classify each of the following reactions as one of these fourtypes: • spontaneous at all temperatures • not spontaneous at anytemperature • spontaneous below a certain temperature but not above• spontaneous above a certain temperature but not below See Table17.1 in Tro, Fridgen and Shaw. (a) CO (g) + 3 H2 (g) → CH4 (g) +H2O (g); ∆H = -206.1 kJ; ∆S = -214.6 J/K (b) AgClO3 (s) + CH4 (g) →AgCl (s) + 2 H2O (g) + CO (g); ∆H = -616 kJ; ∆S = 343 J/K (c) CaS(s) + H2S (g) → CaH2 (s) + 2 S (s); ∆H = 317 kJ; ∆S = -157 J/K (d)2 NH3 (g) → N2 (g) + 3 H2 (g); ∆H = 92.2 kJ; ∆S = 198.8 J/K
