Problem on partial pressure

i) Show that the equilibrium constant Kp for the reaction

CaCo3(s) ↔ CaO(s) +CO2(g)

is about unity (i.e. = 1.0) at 895 °C.

ii) If two grams of calcium carbonate are placed in an evacuated container of one litre and heated to 895°C so that the reaction above is in equilibrium, what is the partial pressure of CO2 in the chamber?

iii) What fraction of the CaCO3 will have decomposed to CaO? Neglect the volume occupied by me solid.

iv) What would be the partial pressure of CO2 if 0.5 gram of CaCO3 had been placed in the chamber?
