The reaction between lime (CaO(s)) and carbon dioxide (CO2(g)) forms the predominant mineral in limestone, CaCO3(s), (Delta Hrxn° = −177.1 kJ/mol, Delta Srxn° = −158.2 J/K∙mol). Lime is a key component in making concrete and is made from limestone. What is the minimum temperature required to shift the equilibrium toward lime (CaO(s)) from limestone (CaCO3(s))?
Homework Answers
We know the relation ;
where
is the
change in Gibbs free energy , 
is the
change in enthalpy , T is the temperature and 
is the
change in entropy. If = 0 then the
system is at the limit of the reaction spontaneity, Thus,

When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete — the lime absorbs CO2 from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 750.L and heated to 770.0°C When the amount of CaCO3 has stopped changing, it is...

Calcium oxide (Lime) is usually produced by heating and decomposing limestone (CaCO3), a cheap and abundant mineral, in a process: CaCO3 (s) CaO (s)+CO2 (g) a) Limestone at 25°C is fed to a continuous calcination reactor. The calcination is complete, and the products leave at 900 °C. Taking 1 metric ton (1000 kg) of limestone as a basis and elemental species [Ca(s), C(s), O2(g)] at 25°C as references for enthalpy calculations, prepare and fill in an inlet-outlet enthalpy table and...
