Solve for the AGo*
Consider the reversible reaction in which calcium carbonate decomposes into calcium oxide and
carbon dioxide gas. The production of CaO (called quicklime) has been an important reaction for
centuries.
CACO3(s) CaO(s) + CO,(g)
The AH for the reaction is 177.8 kJ/mol, while the AS is 160.5 J/K mol. The reaction is
endothermic with an increase in entropy due to the production of a gas. We can first calculate
the AG at 25°C in order to determine if the reaction is spontaneous at room temperature.

CACO3(s) CaO(s) +CO2(g)
The AH for the reaction is 177.8 kl/mol, while the AS is 160.5 J/K mol. The reaction is
endothermic with an increase in entropy due to the production of a gas. We can first calculate
the AG at 25°C in order to determine if the reaction is spontaneous at room temperature.
