Here, the electrochemical cell is explained for redox-active ions, introducing a new comparison between the measurement of midpoint potential and the measurement of initial velocity for enzymes. A redox reaction is feasible only if the species which has higher potential is reduced i.e., accepts the electrons and the species which has lower reduction potential is oxidized i.e., loses electrons. Figure 5.5 The Burning of Natural Gas. In reality, you will find that all redox reactions are affected by pH and the concentrations of products and reactants.
