± Gibbs Free Energy: Temperature Dependence Gibbs free energy (G) is a measure of the spontaneity of a chemical reaction. It is the chemical potential for a reaction, and is minimized at equilibrium. It is defined as G=H−TS where H is enthalpy, T is temperature, and S is entropy.

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.

� Gibbs Free Energy: Equilibrium Constant Nitric oxide, NO, also known as nitrogen monoxide, is one of the primary contributors to air pollution, acid rain, and the depletion of the ozone layer. The reaction of oxygen and nitrogen to form nitric oxide in an automobile engine is N2(g)+O2(g)?2NO(g) The spontaneity of a reaction can be determined from the free energy change for the reaction, ?G?. A reaction is spontaneous when the free energy change is less than zero. A reaction...
