can you answer question nine correct, please

(Q74) A certain process is nonspontaneous at low temperatures. Given that AHX = 201.2 kJ and ASPxn = 876 J/K, at what temperature (in °C) will the process become spontaneous? %3D (Report your Celsius temperature to one decimal place --> if your answer has a decimal place of "O" and Canvas chops it off, don't worry about it).

Q ALEKS - Rafia Riaz - Learn A chemical engineer is studying the two reactions shown in the table below. In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 9.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy A.S of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. PbSO₂ (s) + 4H₂O(1) 4H₂O₂ (1) + PbS (s) 2Fe(s) + 3H₂O(l) → Fe₂O₂ (s) + 3H₂(g) Complete the table.
