Ca(HCO3)2(s) decomposes at elevated temperatures according to the stoichiometric equation Ca(HCO3)2(s)-> CaCO3(s) + H2O(g) + CO2(g)

a.) If pure Ca(HCO3)2(s) is put into a sealed vessel, the air is pumped out, and the vessel and its contents are heated, the total pressure is 0.235 bar. Determine Kp under these conditions.

b.) If the vessel initially also contains 0.105 bar H2O(g), what is the partial pressure of CO2(g) at equilibrium?
