For the reaction provided,the rate of disappearance of I^-(aq) at a particular time and concentration is 2.4 × 10^-3 mol/L·s. IO₃^-(aq) + 5I^-(aq) + 6H⁺(aq) → 3I₂(aq) + 3H₂O(l)
What is the relative rate of appearance of I₂(aq) ?

Question

Quizplus · Accepted Answer

According to the balanced chemical equation, 3 moles of I₂(aq) are produced for every 5 moles of I^-(aq) consumed. Thus, the relative rate of appearance of I₂(aq) is (3/5) times the rate of disappearance of I^-(aq). Therefore, the relative rate of appearance of I₂(aq) is 1.44 × 10^-3 mol/L·s (i.e. 2.4 × 10^-3 mol/L·s x 3/5), which is equivalent to 1 × 10^-3 mol/L·s (within the significant figures given in the answer choices). Therefore, the correct answer is D.
