Given the following half-cell reactions: 1) O2+CO(g)CO2(g)+2e 2) 2O2O2(g)+4e 3) 2H2O(g)+CO2(g)+8eCH4(g)+4O2 4) 1/2O2(g)+H2O(g)+2e2(OH) a) Using two of these half reactions, write a balanced full-cell reaction for a fuel cell. Identify which reaction is occurring at the anode and which at the cathode. b) Using two of these half reactions, write a balanced full-cell reaction for an electrolysis cell to produce a fuel (different one that you consumed in your fuel cell). Again identify which reaction is occurring at the anode and which at the cathode
