WebMay 5, 2014 · For irreversible processes (those with sluggish electron exchange), the individual peaks are reduced in size and widely separated. Totally irreversible systems are characterized by a shift of the peak potential with the scan rate: E p = E° - (RT/ a n a F) [0.78 - ln (k o / (D) 1/2) + ln ( a n a F n /RT) 1/2 ] (9) In science, a process that is not reversible is called irreversible. This concept arises frequently in thermodynamics. All complex natural processes are irreversible, although a phase transition at the coexistence temperature (e.g. melting of ice cubes in water) is well approximated as reversible. In thermodynamics, a change in the thermodynamic state of a system and all o…
