Bаrium cаrbоnаte will decоmpоse when heated to produce barium oxide and carbon dioxide as shown in the following reaction. BaCO3(s) → BaO(s) + CO2(g) Given that ΔH° = 269.3 kJ/mol and ΔG° = 218.1 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.
