Sodium carbonate can be made by heating sodium bicarbonate as shown in the following reaction: 2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) Given that ΔH° = 128.9 kJ/mol and ΔG° = 33.1 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.
