For the decomposition of calcium carbonate, consider the following thermodynamic data ( Due to variations in thermodynamic values for different sources, be sure to use the given values in calculating your answer.):
Calculate the temperature in kelvins above which this reaction is spontaneous.
Express your answer to four significant figures and include the appropriate units.
The thermodynamic values from part A will be useful as you work through part B:
Calculate the equilibrium constant for the following reaction at room temperature, 25°C:
CaCO3(s) → CaO(s) + CO2(g)
Express your answer numerically to three significant figures.
