The iodine "clock reaction" involves the following sequence of reactions occurring in a reaction mixture in a single beaker.

1.IO₃( aq) + 5I (aq) + 6H⁺( aq) 3I₂( aq) + 3H₂O( l)

2.I₂( aq) + 2S₂O₃²( aq) 2I( aq) + S₄O₆² aq)

The molecular iodine (I₂) formed in reaction 1 is immediately used up in reaction 2, so that no iodine accumulates. What is the overall reaction occurring in this experiment?

A) IO₃(aq) + 3I(aq) + 2S₂O3₂aq) + 6H+(aq) 2I₂(aq) + S₄O6₂(aq) + 3H₂O(l)

B) IO₃(aq) + 4S₂O3₂(aq) + 6H+(aq) I(aq) + 2S₄O6₂(aq) + 3H₂O(l)

C) IO₃aq) + 6S₂O3₂aq) + 6H+(aq) I(aq) + 3S₄O6₂aq) + 3H₂O(l)

D) IO3(aq) + I2(aq) + 8S2O32(aq) + 6H+(aq) 3I(aq) + 4S4O62(aq) + 3H2O(l)

E) IO3(aq) + 2I2(aq) + 6S2O32(aq) + 6H+(aq) 5I(aq) + 3S4O62(aq) + 3H2O(l)
