Question

The average rate of consumption of Br- is 1.56×10-4 m/s over the first two minutes. What is the average rate of formation of Br₂ during the same time interval?

Answer 1

To determine the rate of formation of Br₂, we can use the stoichiometry of the reaction. From the balanced equation, we can see that 5 moles of Br react to form 3 moles of Br₂. Therefore, the rate of formation of Br₂ is proportional to the rate of disappearance of Br.

Step-by-step explanation:

To determine the rate of formation of Br₂, we can use the stoichiometry of the reaction. From the balanced equation, we can see that 5 moles of Br react to form 3 moles of Br₂. Therefore, the rate of formation of Br₂ is proportional to the rate of disappearance of Br. Since the rate of disappearance of Br is given as 3.5 × 10-4 mol L-1 s-1, the rate of formation of Br₂ is (3/5) times the rate of disappearance of Br:

Rate of formation of Br₂ = (3/5) x 3.5 × 10-4 mol L-1 s-1
