Question

Consider the reaction: CaCO3(s) -> CaO(s) + CO2(g)

Imagine that calcium carbonate and calcium oxide are placed in a sealed and evacuated vessel at

room temperature. The vessel is heated to 1800 K, and the pressure inside the vessel (due to

CO2) rises to 700 bar.

a) calculate K for this reaction at 1800 K on the assumption that the carbon dioxide is an ideal

gas.

b) calculate the fugacity of carbon dioxide gas under these conditions, using the VDW

coefficients.

c) calculate K for this reaction at 1800 K without assuming the carbon dioxide is an ideal gas.
