Question:

(A) Determine ΔrG° at 298.15 K for the reaction 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s). ΔrH° = -1648 kJ mol-1 and ΔrS° = -549.3 J mol-1 K-1.

(B) Determine ΔrG° for the reaction in Example 13-7 by using ΔfG° values. Compare the two results.

Example 13-7 

Determine ΔrG° at 298.15 K for the reaction

2 NO(g) + O2(g) - 2 NO2(g) (at 298.15 K) A,H = -114.1 kJ mol-1 A,S-146.5 J K- mol-
