Consider the following reactionoccurring at 298 K: BaCO3(s)?BaO(s)+CO2(g)

A) Show that the reaction is not spontaneous under standardconditions by calculating ?G?rxn.

B) If BaCO3 is placed in an evacuated flask, what partialpressure of CO2 will be present when the reaction reachesequilibrium?

C) What temperature is required to produce a carbon dioxide partialpressure of 1.0 atm?
