For the reaction provided,the rate of disappearance of IO₃^-(aq) at a particular time and concentration is 2.3

\times

10^-3 mol/L·s.
IO₃^-(aq) + 5I^-(aq) + 6H⁺(aq)

\to

3I₂(aq) + 3H₂O(l)
What is the relative rate of appearance of I₂(aq) ?

Quizplus · Accepted Answer

According to the stoichiometry of the reaction, for every mol of IO₃^- reacted, 3 mol of I₂ are produced. Therefore, the rate of appearance of I₂ is three times the rate of disappearance of IO₃^-. Thus, the relative rate of appearance of I₂ is 3 x 2.3 F1F1F1S1F1F1F10 10^-3 mol/L·s, which is 6.9 F1F1F1S1F1F1F10 10^-3 mol/L·s (Option D).
