Question

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
