In a methane fuel cell, the chemical energy of the methane is converted into electrical energy instead of heat that would flow during the combustion of methane. Using the half-reactions and reduction potentials given below
a) Write a net equation for the reaction.
b) Calculate the potential for the methane fuel cell.

CO32-(aq) + 7H2O(g) + 8e- -----> CH4(g) + 10OH-(aq) Ero = +0.17 V
O2(g) + 2H2O(g) + 4e- ------> 4OH-(aq) Ero = +0.40 V
