Problem

Calculate the temperature at which the decomposition of calcium carbonate becomes spontaneous.

\text{CaCO}_3(\text{s}) \rightarrow \text{CaO}(\text{s}) + \text{CO}_2(\text{g}) \quad \Delta H^\ominus = +178 \text{ kJ mol}^{-1} \quad \Delta S^\ominus = +164 \text{ J K}^{-1} \text{ mol}^{-1}
