Oxygen generation and reduction(O2 +
4H+ + 4e = 2H2O)involve four electrons.
Tafel slopes of oxidation and reduction reactions were (38
mV)-1 and -(118 mV)-1, respectively.
(a) Which of the four one-electron reduction reactions is the rate
determination step?
(b)Suppose that α=0.5 and find the value of v(Nu).
Explain the meaning of the v(Nu) value obtained in this way.
