19. Chemical Thermodynamics / Entropy Calculations / Problem 7

Using the following reactions and their ΔG°rxn values:

Cr2O3(s) + 3 CO(g) → 2Cr(s) + 3 CO2(g)

Calculate the ΔG° (kJ) for the following reaction (express in one decimal place):

2 Cr(s) + 3/2 O2(g) → Cr2O3(s),         ΔG°rxn = –1058.1 kJ

CO(g) + 1/2 O2(g) → CO2(g),             ΔG°rxn = –257.2 kJ
