Consider the reaction 5br−(aq)+bro−3(aq)+6h+(aq)→3br2(aq) +3h2o(l) the average rate of consumption of br− is 1.20×10−4 m/s over the first two minutes. what is the average rate of formation of br2 during the same time interval?

0.720 M/s

Explanation:

Let's consider the following balanced equation.

5Br⁻(aq) + BrO⁻₃(aq) + 6H⁺(aq) → 3 Br₂(aq) + 3H₂O(l)

The molar ratio of Br⁻ to Br₂ is 5:3, that is, when 5 moles of Br⁻ are consumed, 3 moles of Br₂ are produced. If the average rate of consumption of Br⁻ is 1.20 × 10⁻⁴ M/s, the average rate of formation of Br₂ is:
