Consider the thermal decomposition of calcium carbonate:
(a) Use the data in Appendix B to calculate the standard free-energy change for this reaction at 25 °C.
(b) Will a mixture of solid CaCO3, solid CaO, and gaseous CO2 at 1 atm pressure react spontaneously at 25 °C to produce more CaO and CO2?
(c) Assuming that ΔH° and ΔS° are independent of temperature, estimate the temperature at which the reaction becomes spontaneous.
