Sоdium cаrbоnаte cаn be made by heating sоdium 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.
