Question

Show that the reaction,
CO(g)+12O2(g)CO2(g)
at 300 K is spontaneous and exothermic, when the standard entropy change is 0.094 kJ mol1K1. The standard Gibbs free energies of formation for CO2 and CO are 394.4 and 137 kJ mol1 respectively.

Solution

The given reaction is
CO(g)+12O2(g)CO2(g)
ΔGo(forreaction)=GoCO2GoCOGoO2=394.4(137.2)0=257kJmol1
ΔGo=ΔHoTΔSo
257.2=ΔHo298×(0.094)
ΔHo=285.2kJ
