Ethene, a component in natural gas, can be used as a fuel in combustion reactions. What is the maximum amount of work (in kJ) that could be supplied by the following reaction under the given conditions at 337 K?
C2H4 (g) + 3 O2 (g) ? 2 CO2 (g) + 2 H2O (g)
where ?H = -1323 kJ, ?S = -28.1 J/K, and [C2H4] = 4.75 M, [O2] = 9.57 M, [CO2] = 3.33 M, and [H2O] = 11.73 M.
