Finally, the two half-reactions are combined. The oxidation half-reaction is: C2O4 -2 → CO2 The first step is to balance elements, other than oxygen and hydrogen, using the normal methods of balancing chemical equations. We have two carbons in oxalate, so we need a 2 in front of ...

and, in general, the potential of any half-reaction changes with the concentration of the species involved according to the Nernst equation (7): (7)E=E∘−0.05916nlogQwhere Q has the same form as the equilibrium constant but is a function of the actual activities of the reactants and...
The low activity of the oxygen reduction reaction in polymer electrolyte membrane fuel cells is a major barrier for electrocatalysis, and hence needs to be optimized. Tuning the surface electronic structure of platinum-based bimetallic alloys, a promisin

is named as limiting diffusion current. This current value is obtained when the electrode kinetics is very fast and the reaction rate is controlled by the diffusion of the reactants to the surface of the electrode. This diffusion-limited current can be easily derived using the Levich equation:...
