Rates of Chemical Reaction Lab

Iodination of Acetone

1- a student made up a reaction mixture consisting of 10 mL 4 M acetone, 5 mL 1.0 M HCl 10 mL 0.005 M I2 and 25 mL H2O.

  

  1. Why is the concentration of iodine so much lower than the other reactants?

3. How are time and rate related?   How are 1/time and rate related?

4. What does it mean when someone says a reaction is “first order”?

5. In a reaction, A   +   B   ®   C, it is found that the reaction is first order in terms of A and B. What happens to the rate if the concentrations of A and B are doubled?

Answer #1

Answer 2

Iodine is a reactant as well indicator in this reaction. Absence of iodine indicates that the reaction is completed. The end point is detected by absence of brown color of iodine. If concentration of iodine would have been more color would be darker and reaction time will be more. The color will take longer time to diminish. So, iodine should be less in amount.

Answer 3

Rate and time are inversely related. Higher is the rate, more will be the time required for completion of reaction.

Rate and 1/time will be directly related.

Answer 4

First order means that rate of reaction is directly proportional to concentration of reactant.

Answer 5

Rate = k[A][B]

If concentration of A and B are doubled rate will be four times.
