From These Two Reactions at 298 K

Question 32

Multiple Choice

From these two reactions at 298 K,
V2O3(s) + 3CO(g) → 2V(s) + 3CO2(g) ; ΔH° = 369.8 kJ; ΔS° = 8.3 J/K
V2O5(s) + 2CO(g) → V2O3(s) + 2CO2(g) ; ΔH° = -234.2 kJ; ΔS° = 0.2 J/K
Calculate ΔG° for the following at 298 K:
2V(s) + 5CO2(g) → V2O5(s) + 5CO(g)


A) +133.1 kJ
B) +601.6 kJ
C) -601.6 kJ
D) -133.1 kJ
E) +1.6 kJ
