One compound that is most often used as a biofuel additive for gasoline is ethanol (C₂H₅OH). Calculate the maximum amount of useful work that can be achieved by burning 1.00 mol of C₂H₅OH(g) under standard conditions.

                          ΔG° (kJ/mol)      
C₂H₅OH(g)        –168.5
O₂(g)                    0
CO₂(g)               –394.4
H₂O(l)                –237.13
