Question

3. Which variable(s) in the rate law (rate k [I [BrO [H' may be affected by a change in concentration of the reactants? 5. Which variable(s) in the rate law, rate [ [BrO]" [H , is (are) affected by a change in temperature? 6. Which of the three reactions occurring during this experiment is fastest? 7. Which of the three reactions occurring during this experiment is slowest? Reaction 1 is the slowest: 8. Which of the three reactions occurring during this experiment is the rate determining step? 217

Explanation / Answer

Changing the concentration of the reactants changesc the concentration of the products that they form. So concentration of I-, BrO3- and H+ will change.

The rate constant k depends only on temperature so it will be changed on changing temperature.

The last reaction forming the products should be the fastest.

The reaction which represents the rate equation is the slowest. The slowest step is the rate determining step.
