Calcium carbonate will decompose when heated to produce calcium oxide and carbon dioxide as shown in the following reaction: CaCO3(s) → CaO(s) + CO2(g) Given that ΔH° = 177.5 kJ/mol and ΔG° = 130.4 kJ/mol at 25°C, above what minimum temperature will the reaction become spontaneous under standard state conditions? Hint: Assume ΔH and ΔS are independent of T Hint: Think about the value of ΔG when a reaction goes from nonspontaneous to spontaneous.
