For the decomposition of solid calcium carbonate at 25°C,

(a) Calculate Δ_rG° using values of Δ_f G°. Is the reaction product-favored at equilibrium?
(b) Calculate Δ_rG when the partial pressure of carbon dioxide is 0.10 atm in the presence of both calcium carbonate and calcium oxide. Is the reaction spontaneous under these conditions?
