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 C2H5OH(l) + 2 CO2(g) Calculate delta H^0, delta S^0, and delta G^0 for the reaction at 25 degrees Celsius. Is the spontaneity of this reaction dependent on temperature? The reaction is: a. spontaneous at all temperatures b. nonspontaneous at all temperatures c. spontaneous only at high temperatures d. spontaneous only at low temperatures e. spontaneous only in the reverse direction
