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 ΔH o , ΔS o and ΔG o for the reaction at 25°C. Is the spontaneity of this reaction dependent on temperature? ΔH o rxn = kJ ΔS o rxn = J/K ΔG o rxn = kJ
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
