Question

The redox reaction of peroxydisulfate with iodide has been used for many years as part of the iodide clock reaction which introduces students to kinetics. If E not cell equals 1.587V and E not redox of the anode half cell is 0.536V, what is E not redox of the cathode half cell?

S2O82-(aq) + 2H+ +2I-(aq) yields 2HSO4-(aq) + I2 (aq)

A. -1.051V
B. 1.051V
C. -2.123V
D. 2.123V
E. None of these choices is correct

Answer 1

\(E_{cell}=E_{cathode}-E_{anode}\)

Answer 2

So 1.587V-0.536V=1.051V

Answer 3

yep

Answer 4
