Ethylene (C2H4) plays an important role in the ripening of certain fruits and vegetables. It is sometimes supplemented under controlled conditions at produce—processing facilities but is also produced naturally by many fruit-bearing plants. Although the actual process by which plants produce ethylene is a complex one, imagine that it is produced by the simple breakdown of glucose according to the equation: C6H12O6 (s) --> 3 C2H4 (g) + 3 O2 (g) Given S°= 212.1 J/molK, ▲G°= -910.56 kJ/mol and ▲H°= -1274.5 kJ/mol for C6H12O6 (s). a.) Determine the sign of ▲S° for the reaction. b.) Calculate ▲S° for the reaction. c.) Using the tabulated ▲G° values in the appendix, calculate ▲G° for the reaction. d.) Above what temperature (in °C) is the reaction spontaneous? Hint: you will first have to calculate H° using tabulated values.
