So I had to calculate the Gibbs Free energy for all the reactions: Ca(s)+CO2(g)+12O2(g)→CaCO3(s) = ΔG∘ = -734  kJ   CaCO3(s)→CaO(s)+CO2(g) = 131  kJ CO(g)+H2O(g)→H2(g)+CO2(g) = -28.6 KJ but now I have to predict what lowering the temeprature will do to Gibbs Free Energy: it will decrease with decreasing temp. ΔG∘ will increase with decreasing temperature. ΔG∘ will change slightly with decreasing temperature.
