7), we notice that as we increase the partial pressure of both hydrogen and oxygen the potential gets more positive indicating that the reaction is more energetically favored. It is worthy to spend some more words on the dependence of the cell potential on the temperature. Such a dependence is more subtle than what is suggested by Eq. 5). Basically this is because even the term E0 is affected by the temperature. The dependence of E0 on the temperature may be accounted for by applying Eq. 8).

Under convection it is possible to replenish (or remove) chemical species from the electrode–electrolyte interface. , in the case of the rotating disk experiments which will be discussed later. 3 Electrochemical Kinetics 37 It is worthy to mention that diffusion phenomena may significantly be hampered in certain nanoarchitectures. This will be discussed in some detail in Chap. 4. 3 Adsorption We have seen that adsorption occurs within the Helmoltz layer. Such a stage is often determining for the rate of electrochemical reactions.
The reader interested in a deeper understanding of both the thermodynamics of the electrochemical cell and electrochemical kinetics is instead referred to excellent specialized monographs [2, 9]. , Hydrogen Evolution Reaction (HER), Hydrogen Oxidation Reaction (HOR), Oxygen Evolution Reaction (OER), and Oxygen Reduction Reaction (ORR). Alcohol oxidation reactions and CO2 reduction will also be covered. Each of these reactions has been extensively investigated in the literature, leading to an enormous volume of articles and reviews.
