SOLVED: The redox reaction of peroxydisulfate with iodide has been used for many years as part of the iodine clock reaction, which introduces students to kinetics. If Eocell is 1.587 V and E° of the cathode half-cell is 0.536 V, what is E° of the anode half-cell? S2O8(aq) 2H 2I-(aq) -> 2HSO4(aq) I2(aq)-1.051 V-2.123 VC1.051 VD2.123 VNone of these choices is correct.

The iodine clock reaction is a classic chemical clock demonstration experiment aimed at displaying chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886[1],[2]. The iodine clock reaction exists in several variations, each involving iodine species (iodide ion, free iodine, or iodate ion) and redox reagents in the presence of starch. Two colorless solutions are mixed and, at first, there is no visible reaction. After a short time, the liquid suddenly changes to a dark blu
