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
