1)
ΔH = -683.0 KJ/
ΔS = -366 J/K
= -0.366 KJ/K
use:
ΔG = ΔH - T*ΔS
ΔG should be negative
that is ΔG<0
since ΔG = ΔH - T*ΔS
so, ΔH - T*ΔS < 0
-683.0- T *-0.366 < 0
T *0.366 < 683.0
T < 1866 K
Answer: below 1866 K
2)
ΔH = 181.0 KJ
ΔS = 24.9 J/K
= 0.0249 KJ/K
use:
ΔG = ΔH - T*ΔS
for reaction to be spontaneous, ΔG should be negative
that is ΔG<0
since ΔG = ΔH - T*ΔS
so, ΔH - T*ΔS < 0
181.0- T *0.0249 < 0
T *0.0249 > 181.0
T > 7269 K
Answer: above 7269 K
