Be sure to answer all parts. The U.S. requires automobile fuels to contain a renewable component. The fermentation of glucose from corn produces ethanol, which is added to gasoline to fulfill this requirement: C6H12O6(s) → 2 C₂H₂OH(1) + 2 CO2(g) Calculate AH, AS° and AG° for the reaction at 25°C. Is the spontaneity of this reaction dependent on temperature? ΔΗ rxn =-68 AS 0 rxn AG° = J/K rxn =-227.9 The reaction is: spontaneous at all temperatures nonspontaneous at all temperatures spontaneous only at high temperatures spontaneous only at low temperatures spontaneous only in the reverse direction
