Refer to the tabulated values ofΔG°fin Appendix IVB in the textbook to calculate E°cell for a fuel cell that employs the reaction between ethene gas (C2H4) and oxygen to form carbon dioxide and water (gaseous).
Balanced Equation: 2C2H4(g) + 3O2(g) ---> 2CO2(g)+ 2H2O(g)
Values: C2H4 = 68.4 kJ/mol, O2 = 0kJ/mol, CO2= -394.4 kJ/mol, H2O= -228.6kJ/mol
