1. The reaction ½ 0zc@) + Hzc@) → H20a) is used in fuel cells to produce an electrical current. The reaction can also be carried out by direct combustion. Thermodynamic data: molar entropies in J mol-! K-': Oz1) 205.0; H29130.6; H2O, 70.0; H2O(!) AH®¡= -285.9 kJ mol-. Use this information to find a) The amount of heat released when the reaction takes place by direct combustion; b) The amount of electrical work the same reaction can perform when carried out in a fuel cell at 298K under reversible conditions; CI The amount of heat released under the same conditions.
