Question

Consider the reaction:   5Br-(aq) +BrO3-(aq) + 6H+(aq) ---> 3Br2(aq) + 3H2O(l) The average rate of consumption of Br- is 1.75 x10-4 M/s over the first two minutes. What is theaverage rate of formation of Br2 during the same timeinterval? Express your answer numerically in molar per second.

What is theaverage rate of formation of Br2 during the same timeinterval? Express your answer numerically in molar per second.

Explanation / Answer

5 moles of Br- are consumed as 3 moles of Br2 are formed 1.75 e-4 M Br-/s     *   ( 3 Br2 / 5Br-) = 0.000105 M /s = 1.05 x 10^-4 M/s
